After insurance no dust on my screen (Sony HX50V) and no humidity, I separated the two parts of the protective film (in the heat of the moment, the party and keep the shed are not identified, I had a few seconds of hesitation). I then applied the party keep on my screen smoothing slightly from the inside to the outside. Awesome! no bubble! these transparent protections have pretty thick air without altering the vision and apply very well. The price of 6 is very competitive! But be careful: they send a plain envelope DL22 miss it just a box to stiffen the whole. I just removed one star because I do not know, of course, also be subject if it has scratches quickly in time. So you can buy. no pb. serious seller, fast, cheap. who says better?
