I have since repented.
Every time I re-start writing with this keyboard lacks a registered tipptes word or more. the response of the wake-up is too slow. also in the middle of writing suddenly missing typed letters or leerrräume, and can be used only with difficulty by multiple touch.
all this and more are to be unnecessary blemishes that could iron out a good technical service.
However, this service does not exist. he does not answer requests to appropriate, pretends to be dead. So I get rid of this, only externally beautiful, keyboard probably have to send them back.
