I have had my Droid for just about four months now. The day I bought it, I went to my local mall and had the kiosk guy put the invisibleSHIELD screen protector on it like I've done with all my other phones. A few weeks later, I took my cousin by to the same guy so he could get a screen protector on his and the guy offers to do the full body protection for $10. I agree.
The screen protector is doing great. No problems whatsoever. The full body protection is a little different. The tiny piece next to the power button came off, and the short piece to the left of the charging port moves around. When it was applied, you could not see the pieces at all. After a couple months of bouncing around in my pocket and so on, you can now see the edges on a few pieces. It almost looks like the pieces are outlined in a fine white line. A couple of the corners started to peel back where the two different pieces meet.
I'm not complaining or bashing the product. I love invisibleSHIELD. I'll buy a screen protector from them when I get my Nexus One. I just wanted to give everyone a heads up on my experience in case anyone was considering this purchase. I would still recommend them overall.
