I ordered from mobile fun. Upon instalation I noticed I had a hairline scratch on my screen, which is crazy annoying since it hasn't touched anything besides maybe cloth and plastic. Also when taking off the "part 2" protection, doesn't use a fingernail to smoothen out the bubbles. I fortunately only did it at the top where the part 2 tabs are since bubbles get caught under there and you can't move it unless you remove that protector piece.
Also seems to work fine with an otterbox commuter case. Just make sure the rubber part on the top, bottom and sides go over the screen protector. Then put the plastic piece on.
