Do yourself a favor and read all the poor reviews. Do not buy this. If you do buy it make sure you put a micro fiber cloth on the keyboard when you are done using it. I was fortunate to be using glass protector on my iPad so I just replaced that, but it was severely scratched. It does a poor job protecting your screen.
Logitech has not responded to support request after sending pictures and escalating the issue. They have been dealing with too many repairs and stopped caring.
