The battery charger I use only for charging. I want to conserve battery power and have not always fully charged. It securely holds longer if discharges only when necessary recharges him gradually and again. The first charging takes about a day, but I find it okay. After the battery charge lasts for about a week with normal use. I find that very acceptable.
The processing of the brush is high. It makes me feel as if they a while - would hold - so at least two to three years. Operating sound can be powerful, perhaps a bit too loud, but the result so the tooth cleaning itself is really good. Thereon to kommts in such a device.
The Trizone brush head is great, but makes for a good cleaning result. I like him much better than the usual rotating round head. By Trizone my teeth feel to even cleaner and smoother.
Finally I can say that the Oal B Trizone is a recommended toothbrush. Buy recommendation!
