Affiliate disclosure

This site is reader-supported. If you click an outbound product link and buy something, we may receive a commission from the retailer or manufacturer at no additional cost to you.

We participate in the Amazon Associates Program. As an Amazon Associate we earn from qualifying purchases. Our #1 pick is sold directly by its manufacturer, and that link is also commissioned.

Commission rates differ between merchants. We are aware that this creates an incentive, so the scoring model is fixed and published on the About page before products are scored, and rankings are not sold.

Prices and ratings for competitor products are taken from the retailer's own page and stamped with the date they were checked. Where a merchant does not publish a numeric price, we say so rather than inventing one.
