I was very disappointed at first products of big ben and I still try another brand, every time I fell against the same pitfall, namely, the micro dust that stick to the film sticker few seconds before gluing . Yet each time I cleaned the surface with alcohol, the last time I even wore latex gloves, my desperate excessive static electricity even after passing under the water was right in my attempts .. because when film made magnet, it's game over, you can not make up for it. Here it almost completely market ... so I guess it will work with less electric hand ... the +: a membrane semirigide good bill and a simple method of installation time 2 the -: the offset on the sides of the keys was much less easy to keep clean areas without microparticles (for me it is frankly on these sides that this has spoiled) finally I bought two high-end of a video game store famous large-area product which only covered the touch screen, and there it worked 100%
