Review (5/5): You won't regret this purchase
I'm giving this item 5 stars, though I do agree with what a previous reviewer said - it does get sloppy near the base of the charger. You have to keep on top of that if you don't want paste buildup there. For me the buildup has never affected charging.
However, the list of positives is strong. I had a previous model of Oral B electric and this one is cheaper and even better. It works like a charm. A nice feature is that it lets you know when you've been brushing for 2 minutes. That may sound silly to some people but most people do not brush long enough. A scrub here and a scrub there and they think they're done because their mouth tastes minty. This gets your teeth CLEAN. After I had this brush for a few months I had a dentist visit. He asked me if I had gotten my teeth whitened! (I hadn't and I don't use any special toothpaste. I just brush with this for the two minutes.)
This product is excellent and really works well.
By the way, I still have the other Oral B I mentioned and it still works, after about 8 years.
