Review (1/5): Whitens teeth, takes forever to charge
I had high hopes for this product. I used it once and there was a noticeable difference in the color of my teeth. However, it takes FOREEEEEVER (insert Sandlot reference here) to charge. And you have to charge it prior to EVERY use. I started charging it when I woke up in the hopes I could use it before I went to work. It’s still charging, an hour later, which isn’t convenient at all. Not sure this is worth 140 bucks.
