i ruined and threw away my first invisible shield after failing to apply the first piece properly...

but decided to buy another one, this time i was a little more liberal with the spray, and i'm pretty satisfied about how it went on my storm...

although not perfect, it does protect the phone's surfaces which is what it's purpose is...

i do have a few suggestions and comments, comments first:

the parts of the shield that are meant to protect the top and bottom silver bezel on the phone (when looking at the phone in portrait view) would not adhere to the curved surface, no matter how much palming and fluid i sprayed...i simply sliced those parts off with a sharp blade. the left and right sides were easier to adhere. this could probably be because of the curvature differences of the top and bottom vs. left and right.

suggestions:
the shield does not need to have a cutout where the LED, Camera and flash are located. i applied the shield with these cutouts still in place and it does not affect functionality of those areas.
the shield could also benefit from a thickness reduction, it would make curved surfaces easier to adhere to and apply.

perhaps you can make a pre-shaped shield ? something like that could come in less pieces, and protect more of the phone than the current shield....
