First off all I tried applying the tape to the original foam. Didn't stick very well and made the screen much rounder. Lucky I brought 2 of these so I then removed the original foam and the tape applied well and the cover fit well.
I did cut out the bottom nose part like mentioned in other reviews and I think its much better. Not sure why the design is this way but it is fixable.
You do need to be careful when removing the cover otherwise you can rip off the tap as well and then it wont stick back on the same.
Lastly there is no instructions but make sure to remove the plastic frame, makes applying it much easier.
