## What reviewers say

**BURST Water Flosser** — Good Housekeeping is the only whitelisted outlet to hands-on test the exact BURST Water Flosser. It was among the dozen flossers evaluated by its Beauty Lab and 119-person consumer panel, but it landed in the 'other models we tested' group that did not make the final cut. Testers praised its affordability and flexible tips that rotate a full 360º (useful for the back of the mouth and for braces), but faulted the small 110 mL tank's frequent refills and messy use.
