Take the time to apply them and you will succeed. It is great. I bought these for my first Switch and only used one so I gave the second one to a friend - it seemed to have a bit of trouble keeping the edges from lifting. You have to align them very carefully, but once they're aligned I think they're great. Good enough that when I upgraded my Switch to the version with extra battery life, I bought another bundle. Glass picks up stains because it's glass, but they wear out immediately. Installation Tip: If you accidentally messed up the screen and want to lift the screen protector to reposition it, *don't* try to lift it with your fingernail. Instead, take a small bubble-breaking plastic card from its packaging, tuck a corner under the protective sheet, and *very slowly* lift it up that way. For example, let the tension of the glass itself rise and wait for the glue to come off in time. When I installed one of these on my new Switch I was tired and impatient and had to reposition it about 3 times, but removing the protective film with a plastic card worked great and didn't damage the adhesive at all and the glass is perfectly intact; all edges of the tread are perfectly glued without any traces of glue. Move as slowly as possible and you should be fine. See the photos of the corners I had to lift several times with no signs of wear. Also, no blisters. Note: I did not use stickers. I used alcohol wipes (well, just one of those, there's one for each protector) and a microfiber cleaning cloth.
