I was really looking forward to protecting my screens so when I got the guards I immediately wanted to put them on my phone. Unfortunately they come with a sticker on the front that leaves way too much residue. I tried to rub out the residue with warm water and a towel, it just got worse. I tried to use nail polish remover (carefully) to take the residue off and it still wouldn't come off! After this whole process the screen was full of my fingerprints and residue all over! I had to throw them out because there was just no way of getting them clean!
