Hi there, I'm about to order Best skin ever tommorow, since IS is so expensive =\. Anyways I want to ask is it REALLY true 100% there same material? Questions : 1. Do bestskinever prevent scratches/ fingerprints? 2. Do Invisible shield prevent scratches/ fingerprints? 3. Why do I have to let it dry for 24hours after applying the protective? 4. How long does these things last (BSE)? 5. Are there any risk/ dangers into breaking the ipod touch from applying these protective covers? 6. Do the corners match up of the BSE?
