Just finished up a tedious Clarivue ultra-clear screen protector installation. Right now $10.99 USD for two protectors:

Slightly overshot one of the corners and ended up scorching the first attempt. Second attempt successful after employing the scotch tape method of dabbing off a few annoying bubble-causing flecks.

Clarity is very good... ultra-clear as stated. Strong static bond to the screen. So far it has a nice smoothness - similar to the actual screen but a bit harder and with a little less resistance to the stylus. Recommended
