I bought this toothbrush on a whim. I had tried other electric toothbrushes before and were moderately satisfied by them, but never felt like they were doing that great of a job. This electric toothbrush on the other hand really feels like it is cleaning my teeth.
My toothbrush came with a uv cleaner on it, so that every now & then, you can get a good cleaning and remove all the germs that builds up in your brush from sitting in a bathroom.
One thing I love about this brush is that is oscillates at such a high speed that it really feels like your teeth are getting clean without you having to do much work. At first, I didn't like how much it vibrated, but quickly got used to it and enjoyed it. The first time I used it, I made the mistake of putting the toothpaste on the brush and turning it on before sticking it in my mouth. Needless to say it was powerful enough to toss my toothpaste right off the brush.
The battery life lasts for a good bit of time before the toothbrush requires charging, but its easy enough to let it sit on it's base and charge overnight or while you are at work.
The only thing I don't like is that the toothbrush doesn't fit securely on the base and it can get knocked over fairly easily.
