Review (2/5): Too weak to be useful
The only feature I like about this product is its portability. The rest is sub par. Mainly, this product does not have enough power to adequately clean gums and teeth. After six months of daily use, it made absolutely no difference to my oral health. I replaced it with a waterpik that has 10 power settings, and I immediately noticed a world of difference. The waterpik is roughly twice as expensive, but at least it has an effect. In comparison, this cordless teeth cleaner was an utter waste of money.
