After reading the reviews for this and the 400 model, I bought this toothbrush last week to replace a much costlier sonicare. I prefer the sonicare but at the price this one cannot be beat. It works fine and does the job at a much lower cost.

This toothbrush works just like you might expect it to, without any fuss. It vibrates up-and-down. It does not spin round-and-round.

I have used mine for two years, and only once had a problem. The brush started to wimp out on me, but then I noticed I had unplugged the charger.

You can spend a lot more $$ to get a fancier brush that works no better, or you can spend a little less to get a round-and-round brush that is no more effective than the kind that work without a battery and cost only a buck or two.

We've used the Waterpik electric toothbrushes for over 15 years and are always disappointed when they "retire" a model because we either need only a new handle (the nicad batteries don't last forever) or a couple more brush heads. But every replacement model is just as good as the original and the DT-300 is no exception.

We like it because it has the normal "toothbrush" shape to the brush head and the holder (two brushheads) is small so that it doesn't take up much room on the vanity. It cleans our teeth well and it's comfortable to hold.

About the only downside is that I have a small mouth and the brush head sometimes hits my teeth making a 'klunk' sound. It took me a few times to figure out what was happening and now I try to keep my mouth open wider. I can't actually feel it when it does this, just hear a small bump sound.

At the price, it's a super deal.
