Review (5/5): I'm happy.
First time ever I use an electric toothbrush as others are too expensive for me. This one is more affordable and should give it a trial. Since I have no other comparison, I cannot say if this is better. I carry with me as I travel. I believe I can use in both US and Europe. If my teeth are cleaner? I guess it is the same just I do not need to move that much and there seem to have a timer. It also depends on what toothpaste we use. Mine is a good one.
With no indication if there is enough battery, I just keep charging it ever other day. Will this become overcharge? I do not know.
After all. With the price, I am happy so far.
