I purchased this for my ASUS ZenPad Z300m but had to return it after the corner piece caused my tablet to reset three times.
Because of the position of the corner straps, the power/sleep button or the volume buttons are constantly being pressed. If it's not the one, it's always the other. Also, the lower corner strap gets in the way of charging port. I had to remove that corner in order to properly charge the ZenPad 10, otherwise I was fearful it would put too much strain on the port causing the port to prematurely wear.
If you don't have an ASUS ZenPad 10, give it a try; it may work well for you. But for me, it didn't play nicely so it had to go back.
