I have been using the G3 screen protectors for about a month now and it works for the most part. I has some funny rainbow glare to it if you hold it up just right. Also the screen likes to slide up and left a bit, making it act completely crazy when you put slight pressure to the left edge of the phone (ie. holding it normally). It can cause the protector to press down on the screen.

Does the boxwave crystals do the same thing? I was thinking about giving them a try. If they are the same in principle, I would expect the same to happen. Any comments?
