Goes on easy and protects the screen. Makes sure if you have pets that shed that you remove clothing that has pet hair on it or it can cling to the protectors back side when putting it on making you have to remove it and try to scrape off foreign objects. Also make zure to wash your hands, work in an environment free of debris and is clean, and to spray your hands with applicator liquid to avoid leaving fingerprints on the backside of the protector. If done correctly protector will go on easy and not have any blemishes. Only downside is that the HD protectors seem to be prone to smearing when rubbing your fingers on them when using the device. To get rid of fingerprints and smudges, I just wipe it using my shirt or pants.
