Review (5/5): Durable and works great with rechargeable batteries.
I've been using this for two years. I use rayovac rechargeable batteries, and they last at least a couple of months before needing recharge (use twice a day), so this is even more convenient than the sonicare with the built-in battery. Has been durable, and cleans great--as well as the other sonicare toothbrushes I have owned.
