Review title: It Works!
Product review: My girlfriend and I share the brush, we just switch between two heads which is just a simple matter of screwing and unscrewing. Why pay for two of these at these kind of prices? Function is great, it just runs for 2 min and if you need more time you hit the button again. My dentist wouldn't leave me alone about getting one of these and I have to say, it was worth the investment. My girl is already been telling me her teeth are whiter and glint now and its been just a couple weeks. Skip the higher priced models, they all do the same thing in the end, you just pay for more timers and beeps but the brush still works the same.
