Have tried various screen protectors before and having recently upgraded my phone I wanted something good this time as prior ones hadnt really done the job. A friend recommended Media Devil and I haven't regretted my purchase. Instructions were clear in the packaging, even Youtube guides to help. Aligning and applying the protector was easy with no fuss and done within 10 mins. Had a few air bubbles that were quick to eliminate using the smoothing card. All in all very happy and would recommend Media Devil to others.
