Easy installation and no negative impact on screen use. However, it does not stay in contact at the edges (it comes off), probably due to weak adhesive substance. I used both membranes from the package, but it was exactly the same. It's a shame because it seems like a quality product

The best I have seen in mobile phone screen protectors, incredible packaging with many extra cleaning wipes, instructions, stickers, and many more. It is definitely worth buying.
