My old midprice Oral-B, which has given me some years of faithful service, I had replaced due to a weaker-acting battery by this brush. Stupid, that in this model the battery even innately just as weak. What good is the cheapest brush when I have to do these every 3-4 days for a few hours to the socket. This is not only annoying, but also costly. Therefore Recommendation: direct access to a more expensive model - for the handling, cleaning performance etc. with fully charged battery because there are otherwise no complaints. Or go to the competition. That such a scrap like this comes to the store, namely annoying and the Fa. Brown is not worthy.
