So far I have frequently used films for screen protection. The best is the Clearguard film which is relatively easy to apply good. This GGS screen protector is unmatched, but: Absolutely incomparable good is the mounting of this display protection made of glass. Could not be better. Bubble risk can I detect none, and the screen protector provides this piece of glass in my opinion, better safe than it can be a foil. Also carries on hardly. For micht first choice. Too bad that the touch does not work on the iPod .....
