We have the equipment already in use for half a year and are happy as the day. Despite repeated use per day, the brushes are still like the first day. Although the device is very slim, it feels solid and sturdy, nothing wobbles or shows signs of wear. Despite small size of the battery by holding one week at a 3 times use per day. The only drawback: the NI-MH battery can not be replaced, it should give even his spirit. But that now seems to be standard in many small appliances.
