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.
