Review (5/5): Does a good job cleaning1
I really like this toothbrush. This is the second one like this that I have had. The first one lasted over four years. I opted for the battery operated one because it takes so long to charge the other ones. I bought the Eneloop rechargeable batteries by Sanyo.
I keep one set charged, in a plastic sandwich bag, while the other set is in the toothbrush. I found that if you leave then in the charger, they run down. Also I do take the head off of the toothbrush every time I use it and rinse it off inside, so that it is not gunky.
Works for me!
