Affiliate disclosure

We participate in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate we earn from qualifying purchases.

Some products — including our current #1 pick — are sold directly by the manufacturer rather than through a marketplace. Where we link to those offers we may be paid a commission by the merchant under their own affiliate program.

Rankings, scores and the wording of our reviews are decided before commercial terms are considered, and no brand sees a review before publication. Commission rates differ between merchants and are not a factor in the order of this list. We also list drawbacks for the products we recommend, including the #1 pick.

Prices shown are the figures we verified on the seller's own page on the date stated beside them. Prices, discounts and stock change frequently and the seller's page is always the authoritative source at the moment you buy.

Content on this site is general information about consumer hygiene devices, not medical advice. See our terms for the full position.
