After I had several brewing Electrobrushes in recent years and the battery power has been steadily worse (depending current device, the shorter term), I bought this model of Philips.Putzleistung very good, charging station with integrated UV cleaner something great for travel. Unfortunately, the UV station can not be used separately and can be for example at home while traveling. But what annoys me is the fact that the battery under normal usage and 2 times per day only max. Holds 7 days. As I would have expected a little more. Well, let's see when the battery power continues to decline. Then I'll have to take the warranty service and return the device.
