Philips Sonicare Electric Toothbrush Review

I asked for a Phillips Sonicare electric toothbrush as a Christmas gift three years ago, and have thoroughly enjoyed this product.  I originally picked this product to try based on the fact that family members had already tried and liked this toothbrush.  My teeth feel so much cleaner than they did using a regular toothbrush, and I've had noticeablyless cavities and less tartar buildup.  The toothbrush buzzes to let you know when to switch to a different side of your mouth (it has 4 timed segments every-time you start it) so you know when you've spent enough time on a section of your mouth. I like the fact that it came with a charger (no batteries!) and an extra base and case for traveling.  I think the gift giver bought the set at BJs, not sure if this package is available else where.  The only concern I would voice is that the base does need charged rather frequently; for this reason I leave mine on the charger all the time.  I have tried other electric toothbrush brands and consider this model to be on par with the other brands I have tried.
