How we picked
We look for widely available products that solve a specific, everyday problem, and skip novelty items that tend to end up in a drawer. We don't accept payment for placement, and we don't publish star ratings, review counts or prices we can't keep current. We haven't hands-on tested every product here, so we describe what each one does and who it suits rather than inventing scores. More about how we pick.
