Update (09/20/14)
Meanwhile Spigen I was contacted. The problem is already known and it was offered to me to test the so-called "Button Stabilizer".
This should solve the problem with the usability of the keys! As soon as I receive this I will report on this extensively here!
Update (09/22/14)
The promised remedy, the "Button Stabilizer" were this morning in the mail! DC unpacked and installed and it works perfectly!
Through this tiny buffers that are glued to the inside of these keys have again their pressure point back!
The installation is very simple, stick and go! Many thanks for this Super fast service to Spigen offering the customer immediately!
Instead of me initially awarded 2 stars gets the Spigen Neo Hybrid Case now earned 5 stars!
