Review (5/5): Very effective, more fun than a regular brush
I have used similar brushes, and noticed surprisingly good results from checkups at the dentist's office once I switched from a regular brush to one of these rechargeable motorized ones. Not the ones powered by AAA batteries, I tried one of those when my first Braun brush failed, and it's nothing like this. Not nearly the same power or speed. Since the AAA one was complete fail, I ordered this brush, and it is faster/more powerful than my previous one of the same brand. (The first one lasted for years.) This is money well spent. My mother reported similarly effective results with hers, based on her own visits to the dentist. Planning to buy some as presents in fact.
