the product is not bad ... well fitting, good quality ... the only problem its application! no manual, and especially if you do not succeed the first time and want to readjust the film on the screen, any dust or fiber will stick to the face that is coated with a light glue and create small bubbles unsightly and impossible to remove. Allow 2 packets minimum..dont the first for learning, and prevent dust ... Note that on the back of the iPhone that arises more easily and dust is there are not seen .
