As most others here, I am very impressed by the exterior of the envelope, the fit and the odorless plastic. Most negative reviews come from the fact that the side buttons can be operated only with great pressure. This is true also, but is because the envelope is not applied directly to the studs. It helps a little trick: I have a piece in the size of the respective buttons cut from the adhesive part of a Plasters and glued inside the shell. (Possibly two pieces superimposed) buttons work already now, as without cover, with very low pressure. That reminds me the exterior of the envelope like it very much, I can very well live with this action, and you see nothing more of it. So, rather tinker, be as unhappy!
