Review on InvisibleShield Protective Cowon Screen Clear by Lance Harrison

I got this to protect my covon from scratches and stuff. I'm a little fan of electronic devices, so I've used many types of screen protectors. But it was the hardest screen protector ever. I actually tried applying this to my O2 for about 20 minutes but failed in the end. I used the spray that came in the package and followed the directions exactly, but it was very difficult to do everything without leaving fingerprints and blisters. Went straight to my recycle bin. If you have used it before and know how to use it properly, buy it. But if this is your first time getting this, I suggest you look around for other products.
