This screen protector is pretty cheap, and you should expect to get what you pay for. However, I found that with a couple of modifications, this screen protector worked pretty well.
You will need: Scissors, eyeglasses cleaning cloth, isopropyl alcohol.
Step 1: clean your screen with a tiny bit of alcohol and a eyeglasses cleaning cloth, this works much better than the tiny yellow wipes that come with the screen.
Step 2: carefully cut the corners of the the screen protector to make them a little bit more rounded, hold it against your phone if you have to. Yes, this does mean cutting through the little tabs that help you get the thin protective layers off the screen protector, but if you are very careful, you can still put the screen on pretty easily.
Step 3: put the screen protector on the screen adhesive side down (like you normally would) but be careful to not go over the edge of your screen. You can't really tell at first, but there is a tiny little lip around the screen of your phone and if you go over that lip, you will have bubbles.
Step 4:(Optional) smooth out the bubbles by pushing pretty hard against the screen and moving outward. If you find that you have a bubble next to the side that just will not go away (like near where the speaker goes) gently lift the screen up with your fingernail, and trim the edge a tiny bit with your scissors. This will keep your screen from going over the lip, and therefore remove the bubble.
This seems like a lot of work for something little, but it really only took me 5 minutes to do.
