I posted this in another thread. I figure I would here too.
Be very careful with this product as it CAN DAMAGE your phone!
I've used their products on my camera's for a while. Good protection. However one of these shields ruined my Tilt.
I applied the water to the back of the shield as instructions say, shook the excess water off -- applied to phone screen. Then you take a squeegee and "squeege" the excess water out from under the shield, working bubbles out in the process.
The next day, my LCD was dead. It looked like it had been underwater. My best guess, is that since the Tilt has a bezel around the screen, water actually worked its way in to the phone during the squeegee process, between the LCD plastic and the bezel. It must have leaked down and into the LCD or something similar for video. The colors were washed out and glitchy.
I wouldn't trust this product again on any device that has a screen recessed in a bezel, as theres a high risk water can seep in through the edges. None of my cameras have a bezel'd screen, so I've been lucky with those as they're about $2,300 more expensive then the tilt was.
Just beware. It's a good product, and will resist most scratches, but the water can and will kill your device if it seeps in, which it's almost set up to on the Tilt. Personally I won't use this product on any device that has a bezel such as the Tilt again. The possibility of water leaking through the bezel is too great. HTC did not seal the screen against the bezel and water will leak in.
