This is a really good screen protector. I have tried Samsung's own protector, which had poor instructions and did not fit the phone as precisely as the PhoneDevil. The PhoneDevil Magic Screen Protector was cheaper than the Samsung offering, it was delivered within 24 hours (even with Standard Delivery) so I was fairly impressed the before I even opened the packaging. It was very useful being able to see a video on how to fit the protector (much better than the three sentences on the Samsung branded protector). The Sellotape tip was really good, I'll use that one again. Being shown the best technique in the video meant it was straight forward to fit (given that screen protectors are always a bit fiddly). With all the right tools to hand before you start, and a bit of patience you can get a really great fit. The PhoneDevil also has fewer cut-outs, so less of the screen is exposed when fitted, as compared with the Samsung branded, though it's only about 0.5cm^2 difference, but it's just another little detail that impressed me.
