    After 2 weeks that I bought this toothbrush just stopped charging, I tried in different sockets, I reset the device and nothing happened. The toothbrush cleaned really well my teeth but the battery dies really quick. I followed all the instructions, I fully charged the device the first time. I'm glad I still on the period time to return it to the store because it is very expensive for a toothbrush. Don't waste your money

    Combines the sonicare stroke speed with OralB rotating brush. I've had both in the past, this blows both away.
