Methodology

How products are scored and how prices are tracked.
Scoring criteria are pending; no product has a score yet.

Scoring

[SCORECARD PENDING]

Until the criteria are published, pages show this placeholder instead of a score.

What we list

Checkable facts only: prices, specs, what a device is cleared for (FDA status, where a maker or seller states it), warranty terms and running costs such as replacement pads, batteries and refills. Each fact comes from a maker or seller page. Anything we could not confirm is left out rather than guessed.

How prices are tracked

Non-Amazon prices are read from the seller's own public product page and shown with the date last checked and a link to that page. Amazon prices are not shown; those products have a Check price on Amazon button. Any price not in the price tracker shows "Check current price".

What we do not do

No medical advice, treatment claims or health-benefit claims. Product pages describe what sellers and makers publish.
