How we reached each verdictThe numbers behind each model's score
Philips Sonicare Cordless Power Flosser 3000

Reliability is the weak point, scoring 48 out of 100, with 21% of owner comments mentioning failures and 17% specifically saying the unit broke or died. We analyzed 2,062 star ratings, and 11% were 1-star, which is consistent with those durability complaints.
