Addendum 17:06:14: was contacted by phone, that I because of the poor vote, a new transparent and even a new black get sent!
Let's see how that holds up transparent. currently there for customer service one star more! 4/5 stars!
Addendum 8/25/14: nachgesandte the transparent shell is also turned yellow again after just 2 months. Who can put up with it I recommend buying. who a transparent as ordered would have longer - stay away!
