Handling and cleaning results are really great. An absolute disaster is the build quality. From now 5 brushes of this type are for 1-3 years, all useless. When a battery is over, although he was treated very carefully. For all the brush head is no longer fixed on the device, what does it matter that triggers a screw inside. With a lot of tinkering to get the brush, can tighten the screw again, but helps only briefly. Repeated opening is not possible without damage to the housing. Fazit1: After more than 3 years total loss of 5 brushes! Fazit2: Never again Philips toothbrushes, but they are too expensive!
