Review (5/5): Really Whitens
I bought this a while ago for a travel toothbrush for work so I can floss and brush after having lunch. It holds a single charge a really long time with a full charge (2-3 months using it once a day). The different settings on it are highly effective, and I use the whitening setting and see a visible difference between before and after.
My son (elementary school age) saw it and kept asking to use it, and I kept saying no. One time we were out of the house and he needed a toothbrush so I let him borrow it and he loved it. He kept bugging me, so I got one for him at home and he loves it. We are both very happy with this toothbrush!
