I welcome only that you remove brush cushion and can thus fairly simple and easy to clean. For my quite long and thick hair, this brush is much too small and too unwieldy. Had she convinced me in the size and handling, then I would have probably even keep and maintenance used only without battery operation. So I'll stay, but now with my hand-operated paddle brush and if times the hair protrudes slightly, then that's just like that.
So I personally feel that a battery brush the "miracle ion" sprays out, pretty much is the most superfluous thing I come across in recent years, in addition to the new, speaking rubbish bins in our city, the "thank you" or "Feed me" say!
Quite apart from environmental considerations, when one thinks of this battery history ...
