There are two variants of this charging point - even with 0.9W and once with 1.2W, which are not compatible. Older brushes (mine is from December 2011) require 1.2W. But I got a charging station with 0.9W and had to send them back. According to retailers, there is no 1.2W charging stations more. Because there was no reference to this matter and because of the incompatibility there is a bad review.
