Car Air Freshener Oil: 7 Best Picks That Actually Work (2026)

If your commute smells more like a gym bag than a road trip, the fastest fix is usually a good car air freshener oil. Car air freshener oil refers to any fragrance product — vent clips, cup-holder cans, cartridge diffusers, sprays, or smart plug-in diffusers — that uses a liquid fragrance concentrate instead of a solid gel or a one-time aerosol blast to release scent gradually over days or weeks. That slow, steady release is exactly why oil-based formulas have become the go-to category for drivers who don’t want to think about their car’s smell more than once a month.

The problem is that “car air freshener oil” covers a huge range of products, from a $3 spillproof can to a $45 app-controlled diffuser, and they don’t all perform the same way. A cheap vent clip that dries out in two weeks isn’t actually cheaper than a slightly pricier option that lasts two months. Scent throw, cabin size, climate, and how often you run your AC all change which product makes sense for your specific car.

We dug into real spec sheets, verified pricing on Amazon (amazon.com) and other major retailers, and pulled together aggregated customer sentiment from thousands of reviews to rank seven genuinely good options — from drugstore basics to enthusiast-grade JDM cartridges to smart diffusers. Below, you’ll find a quick comparison table, in-depth breakdowns of all seven picks, a full buying guide, and answers to the most common questions shoppers search for before buying a car air freshener oil.

Quick Comparison: Best Car Air Freshener Oil at a Glance

If you’re short on time, here’s the fast answer. This table pulls out the standout pick in five common shopping scenarios, based on the deeper analysis below.

Looking at the table above, the Chemical Guys New Car Smell Premium Air Freshener earns the “best overall” nod because it balances price, coverage, and genuinely large review volume, while the California Scents Xtreme Can is the easiest entry point if you just want to try an oil-based freshener without committing much money. Drivers in hot, sun-baked climates should pay close attention to the Air Spencer CS-X3, since aggregated owner feedback consistently points to it holding scent longer than drugstore alternatives once cabin temperatures climb.

Top 7 Car Air Freshener Oil Picks: Expert Analysis

We evaluated dozens of real, currently available products before narrowing this list to seven that represent the best mix of value, format, and fragrance performance across entry-level, mid-range, and premium price points. Here’s the full breakdown, including honest pros and cons for each.

1. California Scents Xtreme Can — most affordable spillproof option

The California Scents Xtreme Can is the easiest, cheapest way to dip a toe into oil-based car scenting without committing much cash. Each 1.83 oz can uses a scent-control cap you rotate to adjust intensity, and the brand states the formula packs roughly 25% more fragrance oil than its standard Car Scents line, with a rated scent life of up to 60–100 days depending on conditions. In practice, that vented-lid design means you’re trading raw fragrance power for portability — it’s meant to tuck into a cup holder or slide under a seat rather than clip to a vent, so it disperses passively instead of pushing scent through the airflow. This makes it a smart pick for anyone who wants set-and-forget simplicity rather than a strong hit of fragrance every time the AC kicks on. Aggregated customer reviews across major retailers put this line consistently around a 4.4-star average, with buyers frequently citing the spill-proof can and adjustable cap as standout features, though some note that scent intensity fades faster than advertised in hot-climate daily driving.

Pros:

• ✅ Genuinely spill-proof, cup-holder-friendly design
• ✅ Adjustable vented lid lets you dial in intensity
• ✅ Long unopened shelf life, so multi-packs don’t go to waste

Cons:

• ❌ Scent fades faster than the rated 60–100 days in hot climates
• ❌ Passive dispersal means weaker throw than vent-mounted formats

Price runs around $3–$5 per can, or roughly $12–$19 for a multi-pack — for the money, it’s hard to find a lower-risk way to test whether oil-based scenting works for your car.

2. Little Trees Vent Clip — iconic brand, budget-friendly multi-packs

Little Trees Vent Clip takes the brand most Americans grew up seeing hang from rearview mirrors and adapts it into an oil-reservoir clip that mounts directly on your air vent. Instead of ambient diffusion, the small absorbent pad inside is saturated with scented oil that releases fragrance the moment your fan pushes air across it, which practically means faster, more noticeable bursts of scent than a hanging cardboard tree. The lineup spans dozens of scents, from New Car and Black Ice to more niche blends, and the clip mechanism fits the vast majority of factory vent slats without extra hardware. This is the pick for buyers who already trust the brand and want the vent-clip air freshener oil format without paying a premium — it’s essentially the training-wheels version of the pricier vent-mounted options later on this list. Aggregated review data shows scores clustering around 4.4–4.6 stars across tens of thousands of ratings, with the most common praise being ease of installation and the sheer variety of scents, and the most common complaint being that the oil pad dries out noticeably faster under heavy AC use than under passive ventilation.

Pros:

• ✅ Enormous scent variety across the product line
• ✅ Delivers fragrance directly through vent airflow, not just ambient air
• ✅ Among the cheapest per-unit options in this entire lineup

Cons:

• ❌ Oil pad dries out faster with heavy AC or heater use
• ❌ Scent throw is milder than cartridge-style diffusers

Expect to pay around $3–$7 for a multi-pack, making this one of the lowest-cost ways to try a true vent clip air freshener oil format.

3. Meguiar’s Whole Car Air Re-Fresher Odor Eliminator Mist — detailing-grade odor elimination

Unlike the other entries on this list, the Meguiar’s Whole Car Air Re-Fresher isn’t designed to sit in a vent or cup holder — it’s a single-use 2 oz mist you activate and let circulate through your car’s recirculated air system, reaching the evaporator core, ductwork, and cabin air filter that other fresheners never touch. That distinction matters in practice: because it treats the whole HVAC pathway rather than just the passenger compartment, it’s genuinely designed to eliminate musty AC odors at the source instead of layering a new scent over an existing problem. Professional detailers frequently reach for this exact category of product after treating a car with lingering mildew, smoke, or pet odor, precisely because spot fresheners can’t reach where the smell originates. It’s a fundamentally different job than the vent clips and cans on this list, which is why we’re including it as the “odor elimination” specialist rather than a direct rival to the others. Reviews aggregated from major retailers sit around 4.4 stars, with buyers frequently highlighting how effectively it clears out stubborn AC-system odors, while the recurring criticism is that, as a single-use treatment, ongoing use adds up in cost compared to a refillable clip or can.

Pros:

• ✅ Treats the HVAC system directly, not just the cabin air
• ✅ Actually eliminates odor at the source rather than masking it
• ✅ Backed by a trusted, professional-grade detailing brand

Cons:

• ❌ Single-use format means recurring cost for repeat treatments
• ❌ Requires running the AC/heater system to fully activate

At around $7–$9 per treatment, it’s best used as a periodic deep-clean alongside one of the continuous fresheners on this list, not as a replacement for one.

4. Chemical Guys New Car Smell Premium Air Freshener & Odor Eliminator — best overall value

The Chemical Guys New Car Smell Premium Air Freshener is a 16 oz spray built around an oil-and-enzyme blend that’s meant to neutralize existing odors in upholstery, carpet, and headliners while leaving behind a genuine new-car scent, rather than just perfuming the air on top of whatever was already there. That enzyme technology is the real differentiator here — spraying it directly onto carpets or cloth seats lets the formula break down odor molecules at the fiber level, which is a meaningfully different mechanism than a vent clip that only scents the air passing through it. With over 31,000 aggregated ratings across retailers and an average hovering around 4.2 stars, it’s one of the most reviewed car air fresheners on the market, and that volume of feedback gives buyers unusually reliable insight into real-world performance. Reviewers consistently report that a single 16 oz bottle lasts for dozens of applications, which makes the per-use cost among the lowest of any product on this list despite the fragrance being noticeably strong at full concentration. What most buyers overlook is that this product is doing double duty as both an odor eliminator and a scented oil car diffuser substitute — you’re not just masking smells, you’re actively treating the surfaces causing them.

Pros:

• ✅ Enzyme formula neutralizes odor instead of just masking it
• ✅ Large 16 oz bottle delivers a very low cost per application
• ✅ Backed by tens of thousands of aggregated customer ratings

Cons:

• ❌ Nozzle sprays a fairly direct stream rather than a fine, even mist
• ❌ Scent runs strong at full concentration; many reviewers dilute it

Priced around $6–$11 depending on retailer and size, this is the pick we’d recommend to most shoppers who want one dependable, well-reviewed product and don’t want to overthink the decision.

5. Chemical Guys Vent-Mounted Air Freshener — best for constant, hands-free scent

Where the spray above is an active treatment, the Chemical Guys Vent-Mounted Air Freshener line is a true set-and-forget vent clip air freshener oil, built around a small concentrated fragrance disk that clips into your air vent and releases scent continuously every time the fan runs. The line spans several distinct profiles — Signature Scent, Black Frost, Galactic Scent, New Car Smell, and Tangled Sheets among them — each formulated as a genuinely different fragrance family rather than minor variations on the same base scent, which is a level of differentiation drugstore vent clips rarely offer. Because it mounts directly in the airflow path rather than sitting passively in a cup holder, the scent output scales with how much you run your climate control, which practically means road-trip-heavy drivers get more consistent fragrance than short-commute drivers who barely touch the AC. It carries the same Prop 65 labeling that’s standard across most fragranced automotive products sold in California, which is worth noting for the safety-conscious but isn’t unique to this brand. Aggregated owner feedback describes the scents as bold and true-to-description, with the most common critique being that certain profiles, like the coconut-forward Signature Scent, run intense in smaller cabins.

Pros:

• ✅ Continuous scent release tied directly to vent airflow
• ✅ Distinct, well-differentiated scent profiles across the lineup
• ✅ Compact design that stays out of sight in the vent

Cons:

• ❌ Some scent profiles run intense in smaller or enclosed cabins
• ❌ Carries a standard Prop 65 warning label

Expect to pay roughly $9–$11 per vent clip, positioning it as a mid-range upgrade over Little Trees for buyers who want more distinctive, longer-lasting fragrance.

6. Air Spencer CS-X3 (Eikosha) — strongest scent throw, enthusiast favorite

If you’ve ever ridden in a JDM-inspired build and asked what that distinctive, long-lasting scent was, there’s a good chance it was the Air Spencer CS-X3. Made by Japanese manufacturer Eikosha, this cartridge-style diffuser uses a replaceable oil cartridge — the popular Squash scent (A9) being the best-known — that clips into a cup holder or dash mount and disperses fragrance passively but with noticeably more concentration than typical drugstore products. What sets it apart in practice is refill economy: instead of throwing away an entire unit when the scent fades, you swap in a new $9–$20 multi-pack of cartridges while keeping the original holder, which reduces long-term waste and cost per refresh compared to fully disposable vent clips. Aggregated owner reports, including reviews specifically calling out hot summer performance, consistently describe this line as outlasting typical air fresheners that “die within the week” in extreme heat — a claim that lines up with why it has built a genuine cult following among car enthusiasts rather than just casual buyers. It’s imported, so availability and pricing can fluctuate more than domestic brands, and the upfront holder-plus-refill bundle costs more than a basic vent clip, but the scented oil car diffuser format and refill system make it the strongest scent-throw pick on this list for hot-weather drivers.

Pros:

• ✅ Reputation for outperforming rivals in extreme summer heat
• ✅ Refillable cartridge system lowers long-term cost and waste
• ✅ Cult-favorite status among car enthusiasts for authentic scent

Cons:

• ❌ Import pricing and availability fluctuate more than domestic brands
• ❌ Higher upfront cost for the holder-plus-refill starter bundle

A starter bundle with a holder and a few refills typically runs $50–$60, while refill-only multi-packs land around $9–$20 — a fair trade-off if scent longevity in hot weather is your top priority.

7. Pura Car Diffuser — premium, app-controlled smart diffuser

The Pura Car Diffuser is the only product on this list that turns “car air freshener oil” into a genuinely smart device rather than a passive dispenser. It plugs into a powered 12V outlet and uses an accelerometer to detect motion, automatically switching on when your car starts moving and off when it stops — a feature explicitly designed to conserve fragrance oil rather than run continuously whether anyone’s in the car or not. Intensity is adjustable either through a companion smartphone app or with a physical button that cycles through high, medium, low, and sleep modes, giving far more granular control than any clip or can format offers. Fragrance oil refills, which the brand markets as using cleaner ingredients than typical aerosol formulas, last roughly 30 days per cartridge and come in a genuinely wide range of profiles, including collaborations with recognizable lifestyle and home-fragrance brands. What most buyers overlook with this category of product is that the premium price isn’t really paying for stronger scent — it’s paying for control, consistency, and the elimination of fragrance waste when the car is parked. That said, it’s the most expensive format here by a wide margin once you factor in ongoing refill costs, and it only works where a powered outlet is available, which rules out portable use in a second vehicle without buying an additional unit.

Pros:

• ✅ App and button controls give precise fragrance intensity control
• ✅ Motion-sensing auto on/off conserves fragrance oil automatically
• ✅ Premium fragrance profiles, including recognizable brand collaborations

Cons:

• ❌ Requires a constant powered outlet, limiting portability
• ❌ Highest ongoing cost of any option, once refills are factored in

The diffuser itself runs around $35–$45, with fragrance oil refills typically priced around $13–$18 each — a legitimate splurge for drivers who spend serious time in their car and want set-it-and-forget-it control.

Full Product Comparison: All 7 Picks Side by Side

The table above makes the trade-offs easy to see at a glance: the Little Trees Vent Clip and California Scents Xtreme Can win on raw affordability, the Chemical Guys New Car Smell Premium Air Freshener offers the best cost-per-use of any format thanks to its 16 oz bottle, and the Pura Car Diffuser commands a real premium in exchange for smart controls most other formats simply don’t offer. If hot-weather scent longevity is your main frustration with drugstore fresheners, the Air Spencer CS-X3 is worth the extra upfront cost specifically because its refillable cartridge system addresses that complaint directly.

How to Install and Maintain Your Car Air Freshener Oil for Maximum Scent Throw

Getting the most out of any car air freshener oil comes down to placement and maintenance, not just brand choice — and this is exactly the kind of practical detail an Amazon product listing never covers.

Getting started: For vent clip air freshener oil products, always mount the clip on a lower vent rather than one aimed directly at your face; airflow still carries the scent through the cabin, but you avoid the overpowering blast that comes from sitting inches away from concentrated fragrance oil. For cup-holder cans like the California Scents Xtreme Can, keep the vented lid mostly closed for the first week so the scent doesn’t burn off too quickly before you’ve dialed in your preferred intensity.

First 30 days — common mistakes: The single biggest mistake new buyers make is running multiple fresheners at once — a hanging tree, a vent clip, and a spray — which almost always creates a muddled, unpleasant scent rather than a stronger one. Stick to one primary source and, if you want backup coverage, choose a genuinely complementary scent family rather than doubling up on the same category.

Ongoing maintenance: Rotate cartridge- or oil-pad-based products (like the Little Trees Vent Clip or Air Spencer CS-X3) roughly every 30 days even if scent seems to linger, since oil-based fragrance often fades gradually in a way that’s hard to notice day to day until it’s essentially gone. For smart diffusers like the Pura Car Diffuser, check the app’s remaining-fragrance estimate monthly rather than waiting until you can’t smell anything, since running the device dry can shorten the internal mechanism’s lifespan over repeated cycles.

Optimization tip: If you’re pairing a continuous freshener with occasional deep cleaning, run a single-use treatment like the Meguiar’s Whole Car Air Re-Fresher roughly every three to six months, ideally right after a full interior detail, so you’re eliminating odor at the source instead of layering new fragrance over old smells that are still trapped in your upholstery.

Real-World Scenarios: Which Car Air Freshener Oil Fits Your Driving Life

Not every driver needs the same product, so here’s how the lineup maps to a few common situations.

The daily commuter on a budget. If you’re driving 20–30 minutes each way and just want your car to smell clean without spending much, the Little Trees Vent Clip or California Scents Xtreme Can covers you for well under $10 a month. Neither is going to overwhelm a small sedan, and both are easy to swap out on payday without a second thought.

The family hauler dealing with kid, pet, and snack smells. For cabins that see spilled juice boxes and muddy cleats, start with a Meguiar’s Whole Car Air Re-Fresher treatment to actually eliminate trapped odors, then maintain freshness afterward with the Chemical Guys New Car Smell Premium Air Freshener, spraying directly onto carpets and seats every couple of weeks as new messes happen.

The road-trip and long-commute driver in a hot climate. If you’re logging serious highway miles in a place where summer heat cooks a parked car, the Air Spencer CS-X3 is worth the extra cost — its refillable cartridge system is specifically built to hold up under exactly those conditions, based on aggregated owner reports from hot-weather regions.

The detail-obsessed enthusiast who wants full control. If your car is genuinely your hobby, not just transportation, the Pura Car Diffuser lets you fine-tune intensity by time of day, switch scents seasonally, and avoid fragrance waste when the car sits parked — the kind of granular control a $4 vent clip simply can’t offer.

How to Choose the Best Car Air Freshener Oil

Picking the right product comes down to matching format and strength to your specific car and habits. Work through these criteria in order:

1. Cabin size. A larger SUV or truck cabin dilutes fragrance faster than a compact sedan, so bigger vehicles generally need a stronger throw — think vent-mounted or cartridge formats over passive cans.
2. Climate. Hot climates accelerate fragrance oil evaporation, which is exactly why products like the Air Spencer CS-X3 built a reputation on outlasting rivals in summer heat.
3. Driving frequency. Vent-mounted formats only release scent when your fan runs, so if you drive infrequently, a passive can or hanging option may actually perform more consistently.
4. Odor source, not just symptom. If you’re masking an existing smell (smoke, pets, mildew) rather than just adding a pleasant scent to a clean car, start with a genuine odor eliminator like the Meguiar’s Whole Car Air Re-Fresher before layering on a continuous freshener.
5. Budget vs. refill economy. Compare cost per month, not just sticker price — a $9 refillable cartridge that lasts 60 days is often cheaper long-term than a $3 can you replace every two weeks.
6. Sensitivity to strong fragrance. If you or a passenger gets headaches from strong scents, favor adjustable-intensity formats like the California Scents Xtreme Can or the app-controlled Pura Car Diffuser over fixed-strength vent clips.
7. Portability needs. If you switch between vehicles often, skip plug-in devices like the Pura Car Diffuser in favor of a clip or can you can move freely.

Common Mistakes to Avoid When Buying Car Air Freshener Oil

Even experienced shoppers fall into a few predictable traps when comparing car air freshener oil options.

Assuming stronger scent means better value. A product that smells powerful in the store can overwhelm a small cabin within days, leading you to remove it early and waste most of the fragrance oil. Reviews consistently report that moderate, adjustable-intensity products get replaced less often, which usually makes them cheaper over time despite a milder first impression.

Ignoring climate when picking scent life. Manufacturer scent-life claims are typically measured under moderate, ambient conditions — not a car baking in July sun. If you live somewhere hot, budget for replacing drugstore-tier products roughly twice as often as the label suggests, or upgrade to a heat-resistant cartridge format like the Air Spencer CS-X3.

Layering too many fragrance sources. As covered above, running a hanging tree, a vent clip, and a spray simultaneously almost always creates a muddled scent rather than a stronger one — pick one primary source.

Overlooking the odor source entirely. If your car smells musty from the AC system itself, no vent clip or can will permanently fix it. A single-use treatment like the Meguiar’s Whole Car Air Re-Fresher, aimed at the source, solves problems a passive freshener never can.

Car Air Freshener Oil vs. Aerosol Sprays and Gel Fresheners

Oil-based formulas aren’t the only category on the market, and understanding the trade-offs helps explain why they’ve become so popular for continuous, low-maintenance use.

Compared to a traditional aerosol spray, oil-based products deliver more consistent, less overpowering fragrance over a much longer window, since the whole point of the format is gradual release rather than a single concentrated burst. Gel and bead fresheners land somewhere in between — they last a reasonable amount of time but generally can’t match the stronger, controllable throw that a vent-mounted or cartridge-style scented oil car diffuser provides. The practical takeaway: keep an aerosol spray like the Chemical Guys New Car Smell Premium Air Freshener on hand for immediate touch-ups before a trip or showing, but rely on a continuous oil-based format for day-to-day maintenance.

Features That Actually Matter (and Ones That Don’t)

Marketing copy on air freshener packaging tends to emphasize things that sound impressive but rarely change your day-to-day experience. Here’s what’s actually worth paying for.

Actually matters — adjustable intensity. Whether it’s a rotating cap, a button-cycled setting, or an app slider, the ability to dial fragrance up or down is the single biggest factor in whether you end up happy with a product long-term, since driver and cabin conditions vary so much.

Actually matters — refill economy. A refillable system like the Air Spencer CS-X3 or the Pura Car Diffuser costs more upfront but almost always wins on cost-per-month against fully disposable alternatives once you’re past the first purchase.

Doesn’t matter much — exaggerated “days of freshness” claims. These numbers are measured under lab-ambient conditions and rarely hold up in a hot parked car, so treat them as a rough upper bound, not a guarantee.

Doesn’t matter much — scent name specificity. “New Car Smell” from one brand can smell meaningfully different from another brand’s version of the same name, so aggregated review sentiment about actual scent character is far more useful than the label itself.

Car Air Freshener Oil for Sensitive Noses, Pet Owners, and Smokers

Different lifestyles put very different demands on a car air freshener oil, and matching format to situation matters more than brand loyalty here.

Pet owners dealing with persistent dander and outdoor-dog smells generally get the best results starting with a source-level treatment like the Meguiar’s Whole Car Air Re-Fresher, since pet odor tends to embed in upholstery fibers rather than just floating in cabin air — a continuous freshener alone usually just adds a competing smell on top.

Former or current smokers working to clear out lingering cigarette odor face a similar situation: the enzyme technology in a product like the Chemical Guys New Car Smell Premium Air Freshener, applied directly to fabric surfaces, is designed to break down odor-causing compounds rather than simply masking them, which tends to outperform a passive can or clip on this specific problem.

Sensitive noses and allergy-prone passengers are generally best served by adjustable, lower-intensity formats — the California Scents Xtreme Can‘s vented cap or the Pura Car Diffuser‘s low/sleep settings let you keep fragrance subtle rather than locked at a single fixed strength, which fixed vent clips can’t offer.

Long-Term Cost and Maintenance

Looking at true monthly cost rather than sticker price flips a few assumptions: the Chemical Guys New Car Smell Premium Air Freshener and California Scents Xtreme Can are genuinely cheap to maintain over a full year, while the Pura Car Diffuser carries a real ongoing subscription-like cost once you factor in monthly refills on top of the initial device price. The Air Spencer CS-X3 lands in a reasonable middle ground — a higher per-cartridge price than drugstore clips, but a slower replacement cycle that narrows the gap over several months of ownership.

Safety, Regulations, and Standards

Fragrance products are lightly regulated compared to many household chemicals, but a few practical standards are worth knowing before you buy. Most oil-based automotive fresheners, including several products on this list, carry a California Proposition 65 warning label, which is a disclosure requirement rather than a ban — it flags that a product contains a chemical Proposition 65 considers relevant to reproductive or cancer risk at some exposure level, without necessarily indicating unusual danger for the intended, limited use in a ventilated vehicle cabin.

It’s also worth understanding what’s actually inside these products. A peer-reviewed emissions study analyzing car air fresheners across clips, wraps, cans, and sprays found that the tested products collectively released hundreds of distinct volatile organic compounds, including some classified as potentially hazardous at high concentration — findings consistent with the EPA’s broader research on indoor air quality, which notes that VOC concentrations indoors, including inside vehicles, can run consistently higher than outdoor air. This isn’t a reason to avoid fragrance products altogether, but it does support cracking a window periodically, especially with stronger vent-mounted or cartridge formats, rather than running a sealed cabin with recirculated air continuously.

Product safety issues do occasionally surface in this category as well — the CPSC has previously recalled aerosol air freshener cans over rupture risk tied to corrosion and pressure buildup, a reminder to store any pressurized fragrance product away from direct heat and to stop using any can that appears swollen or damaged. Oil-based clips, cartridges, and cans generally carry lower pressure-related risk than true aerosols, which is one underappreciated safety advantage of the format covered throughout this guide.

FAQs

Conclusion

There’s no single best car air freshener oil for every driver — the right pick depends on your budget, your climate, and whether you’re masking a smell or actually trying to eliminate one at the source. For most shoppers, the Chemical Guys New Car Smell Premium Air Freshener hits the best balance of price, coverage, and proven review volume, while the California Scents Xtreme Can and Little Trees Vent Clip remain smart, low-risk starting points if you’re not ready to spend much. Drivers battling real odor problems should start with a source-level treatment like the Meguiar’s Whole Car Air Re-Fresher, hot-climate commuters get the most consistent long-term performance from the Air Spencer CS-X3, and anyone who wants full digital control over fragrance intensity and timing should look seriously at the Pura Car Diffuser.

Whichever format you choose, remember that intensity, placement, and climate matter as much as the brand name on the label — a $4 vent clip installed correctly can outperform a $40 device placed poorly.
