Honestly, I was a bit reluctant to spray my new screen with whatever it is that they send with the covers but man am I glad that I did it!! I can see the screen great in all but the worst sun and even with it in direct line I can still see it a little. Try that with the manufacturer's screen cover! I bought one and seen that they have some cell phone kits on sale for 7 bucks so I got one of those too. I covered my gps, camera, and video camera screen with just the cell phone kit, of course I had to cut it to fit but hey, I can guess that I saved at least 30 bucks by doing that. This stuff is kind of expensive but is relatively cheap protection for our over priced toys!!!
