After upgrading to the Apple iPhone 4S, I straight away ordered the equivalent protector.
It was a pleasant surprise that there were actually two shields - one for the back and one for the front....They also gave tips on how to recycle the plastic wallet as a photo frame, amusing in a quirky way.
The shields were fitted as soon as the protective packaging films were peeled off.
Was this easy?
No, it was pig of a job to do! Like an earlier reviewer said, ''...take your time...''
I suggest that you fit it in a dust-free room, have freshly washed hands, a scotch tape dispenser to hand and a microfibre polishing cloth. It took me several attempts to centralise the two covers, in that time, a few dust particles had sandwiched themselves in. Also, due to my huge fat fingers, a finger print did appear of the adhesive film. These can be removed by peeling back the shield with a piece of scotch tape and removing the dust/print with another piece, awkward, but works like a dream.
My final and most important tip, is DO NOT try and fit the screens by gingerly holding them at the sides with your fingers; it makes accurate centralising near impossible and when you do so, it will inevitably lead to dust and fingerprints. Rather attach two lightly applied pieces of scotch tape each end, lengthways, peel the shield off the backing using them as anchors and with the iPhone flat on a surface, use the pieces of tape as tools to place the shield,of the screen.
Do not go cheap on the scotch tape either, get the best one that shops 'Sello'.
Overall this is a product very deserving of the five stars, great protection and great durability. Very, very satisfied.
