Review (4/5): I'm happy with this toothbrush...
I wanted to shop around for an electric toothbrush because, despite my best efforts to brush at least twice a day and floss, I still felt like my teeth weren't getting clean enough. My battle involves bleeding gums, which requires that much more cleaning power in between your teeth in order to get rid of the bacteria that's keeping them inflammed. The Vitality brush does a pretty decent job of reaching deep into the surfaces and the spaces of your teeth to get them clean. Licking my teeth, they feel pretty smooth, too.
The toothbrush is recharged with an adapter unit. Remove it from the base, put on your toothpaste, and turn the unit on. The agitation has a little bit of splashback to it, so minimize it by brushing the back of your teeth first and then moving to the front; then the outside surfaces, then the inside. Also, the brush head is fairly small compared to standard brushes. I thought it was a little distracting at first until I started brushing to pay more attention to individual teeth rather than sweeping broadly across them. Finally, I thought the timer was a digital read-out; your brush will vibrate a couple of short pulses to let you know that two minutes is up. It was disorienting at first. I thought the brush was out of power, but I figured it out.
It's a solid investment, and the good thing is that it's relatively affordable and still an effective device compared to more expensive powerbrushes on the market.
