Don't away your money!
I got this product in 9/2008. It worked well but only for about a year. About a year after I got it, the edge around the green power button on the handle began to crack. Now the crack has almost made a complete circle around the button. All this time, it was still functional so I didn't give it much thought about replacing it. Today it just died completely and it has not even been two years yet. My old Sonicare Essence lasted quite a few years without any glitch until the batteries would not hold charge any more. I would go back to the Essence but I am definitely not getting another fanicer model of Sonicare.
