Review (1/5): I PROTEST!
This flosser works as advertised, came promptly, was packaged well, and is probably as good as a manual pump water flosser can be. BUT it had a BIG bright yellow sticker along one entire side of the water reservoir, repeating information detailed clearly in the printed instructions. That sticker was impossible to remove cleanly. Yes, I know about the hairdryer, vinegar, peanut butter, Goo-Gone, and so on. I even resorted to a razor blade. There is still ugly, germ-trapping adhesive on this plastic, which is that particular type that never fully releases a sticker. What I especially resent is the time it took to even partially remove the sticker.
