This screen protector fits on the Samsung Galaxy S4 mini, you should stick it in a cold dust-free environment, the hands should best be free of grease. The first film I wanted to correct again and did not work, thrown away. In the second attempt it worked quite well, no blistering, until the moment when the last adhesive tab should be removed - they clung so strong that the film was removed again in part and the flap went until after several attempts. After almost 4 weeks of film adhere dissolves on the side of a small corner, and she is very scratched, though the smartphone is in a soft shell and I do not often use the device. The films you can buy if you want to change this love often. - Or is that so wanted? - Will use up my last 4 in the near future and then to try another. Despite the scratch you can still see everything, it goes .... but ..... maybe there is something better! therefore only 3 stars
