Really like these products! Affordable and they last a long while. The only reason I’m giving 4 instead of 5 stars is (atleast in my experience) the phone set up can be rather tedious. They set it up so it’s easy to apply but if part of it arrives a little off or a sticker has come off it can be tricky. There’s always a way to fix it of course but it’s happened to me twice with the phone application in particular. The other products like displays and tablets I find are much more straight forward. Again great product and does exactly as it describes, I’ve noticed a difference since applying to my devices.
