I take this envelope since mid-June of 2010. My iPad is regularly used and so some have to suffer. But this cover protects the iPad perfect. Have just times the shell removed (there are from time to time dust particles between the casing and the iPad) and was enthusiastic about the still impeccable back + edges of the iPad. NO scratches or dents. It must also be said that the shell is so thin and light that it almost does not really stand. The iPad can continue to hold great in the hand and I had so far no situation in my iPad, would be due to the envelope, fell down.
The only drawback of this envelope is that it only at the two edge sides small lips has with which it is attached. That falls sometimes on by soft creak or even minimal, brief time loosening of the sheath.
Conclusion: I recommend the sleeve all who are looking for a hidden, lightweight and very good case for your iPad.
PS: the iPad fits defies the SwitchEasy Nude still loose in other cases for transport.
