I never used to think protective skins were worthy to buy. But then one day I saw an InvisibleShield video on Youtube, I was convinced at that point. The thing was like $25, kind of costly for a protective film. Well, after it was shipped to me, I tried to install it for 2 hrs. Those 2 hrs were really nerve racking, I almost gave up cuz everything was a mess, even after that, the air bubbles and unevenness at the side of my Samsung were still noticeable. My phone looked a mess. LOL! So basically, InvisibleShield wants you to hide your phone in public, and went it rings you should wait until your somewhere private before you answer it. InvisibleShield wants people to laugh and stare every time they see your phone! I gave up on InvisibleShield, but I didn't give up on protective skins. I found a better product, Gadgetshieldz, that is really easy to install, no headaches. Now my Samsung looks really polished as if its brand new. I discovered the product at gadgetshieldz.com, it was only $7. I wish I had found out about it since, I wouldn't of wasted my time trying to get InvisibleShield to gel with my Samsung.
