Frequently asked questions

No, and we say so on every page above the first affiliate link. There is no lab, no test bench and no owned units. What we do instead is compile the specifications manufacturers publish, link every source, and do the arithmetic they leave out. The method is set out in full here.

Because you do not have to. Every score comes from one fixed rubric reading published specifications, and the full working for every axis is printed under every product. If you disagree with a weight, the inputs are all there and you can re-run it. A testing claim asks you to trust a process you cannot see; this asks you to check one you can.

Five axes: heat headroom from the published operating ceiling (22%), install effort (24%), list price against a $150 buyer ceiling (24%), warranty length (15%) and how many spec rows the maker actually publishes (15%). An axis with no published input is dropped and the remaining weights re-normalized. The full rubric is here.

Because we have no live price data on this build. The retailer API credentials are not yet active on this account, and the rule is absolute: a price shown next to a buy button comes from the live layer or it does not appear. A remembered price is worse than no price because a reader acts on it. When the credentials go live, the same buttons show real prices with no change to any page.

No, and the pages say so. A list price is what a manufacturer listed on one stated date, and it exists for exactly two jobs: feeding the price axis of the rubric, and deciding which products are eligible for a page like “best dash cams under $100”. It is always shown with its source and its date and it never goes inside a button.

We earn affiliate commission if you buy through a link, at no extra cost to you. No sponsored placements, no paid rankings, no free products. Commission does not decide the order, and the evidence is structural: every ranked page names something to skip, and the top pick on the floor mats page is a maker whose store earns us nothing. Full disclosure here.

Sawyer V. Not a mechanic, not an installer, not a product tester — somebody genuinely interested in how this stuff works, who reads the manuals and does the arithmetic. More here.

Because the makers do not publish those figures. That is the finding rather than a gap in our research: only 6 of the 41 products in this ledger publish an operating-temperature ceiling at all. A blank row costs that product points on the transparency axis, which is the correct incentive.

Prices refresh daily and automatically. Specifications are re-checked when a page is substantively updated, when a reader reports a change, or when a maker revises a page we link to. Every page shows its own real published and updated dates. Editorial policy.

Tell us, and it goes to the top of the queue. A page URL and the figure you believe is correct is enough; a link to the manufacturer's page is better. Corrections get a dated note on the page rather than a silent edit. Contact page.

A phone mount, for almost everybody. Under $25, two minutes to fit, and the only thing on this site you interact with on every single trip. It also has a genuine safety argument, because the alternative is a phone in your lap. The ranking is here.

Yes, and the useful question is how fast. On published figures a camera plus the car's own electronics draws roughly 0.3 A, which is about 43 hours on a healthy battery in mild weather and closer to 17 at -18 C. The hardwire kit's cutoff voltage is what turns that from a risk into a setting. The full arithmetic is here.

Thirty on a USB-C port covers any phone. Phones cap between about 20 and 45 W and above their own ceiling extra watts do nothing at all. The 67W and 130W chargers are for laptops. The arithmetic.

Heat. Adhesive pads and suction cups are rated for a temperature range that a parked car in summer sun exceeds, and the failure is gradual creep rather than a sudden let-go. Three of the fixes are free. Here they are.

It will work and then fail, silently. A dash cam overwrites its entire capacity every few hours, forever, which is the harshest duty cycle flash memory experiences. The gap between the two mainstream endurance cards is 70,080 rated hours against 10,000. The card page.

No. It converts existing factory wired CarPlay or Android Auto to wireless. If your car has no CarPlay at all, no adapter will give it one. The explainer.

No. “Car charger” here means the small adapter that plugs into your dashboard and charges phones. EV charging equipment is a different product category at a very different price and this site does not cover it. This page sorts out which is which.

We cannot tell you that and no product page should. What a cushion does mechanically is change your hip angle and reduce direct pressure on the tailbone. Whether that helps your specific pain is a question for a doctor. What we can do is publish the geometry so you can check it fits your car. The cushion page.

Roughly 60 to 70 C inside on a hot sunny day, with surfaces in direct sun higher still. That is why a published operating ceiling is the most useful number on a dash cam spec sheet, and why so few makers print one. The comparison.

A charged jump starter, a tire inflator and a real pressure gauge, folded reusable bags, a cloth and glass cleaner, a cable that never leaves, a flashlight, and an ice scraper if your winters need one. Seven things. The organizing guide.
