Sourcing
Every device fact links to its source and shows the date we retrieved it: FDA 510(k) records, manufacturer product pages, manuals and instructions for use, warranty and returns pages, and authorised retailer pages. If we can’t source a fact, we leave it out.
How picks are made
Picks come from a published, safety-first scoring method described on How we choose. The same inputs always give the same result.
Affiliate independence
We earn commissions through affiliate links. The ranking code never reads commission data, and a build test enforces it. We accept no paid placements. See the affiliate disclosure.
No hands-on testing, no invented reviews
We don’t test devices hands-on and we don’t say we have. We don’t publish made-up reviews, ratings or testimonials.
Corrections
If something is wrong or out of date, email [email protected]. We check it against the source and fix it as soon as we can.
Updates
We re-check prices and specifications against their sources and show the retrieval date next to each one.
Medical information
Everything here is general information, not medical advice. FDA clearance relates to a specific device and its stated use, and isn’t proof a device works for you. If you have a medical condition, ask your doctor.
