After I had several protective plastic films used on my equipment, I had to renew for scratch again, I opted for this tempered glass sheet. Use the supplied cleaning wipes I cleaned the screen and then placed the tempered glass sheet. Because of my Ungescklichkeit I had the situation repeatedly corrected by reprinting the film that went all problems. Now it fits perfectly, is invisible, the touch sensitivity has not suffered and been without scratches. We recommend !!
