I had high hopes for this product because I liked the idea of a tougher protector. The protector is a little small for the screen and only the edges are sticky. The rest of the protector is not. The package comes with 2 protectors. I made 2 attempts. Followed the instructions and in both cases, i get what looks like an oily bubble between the screen and the protector. I am not sure it is actually an oily substance or just an effect possibly from air between the screen and protector. Both times, I cleaned the screens with the alcohol pad provided, Both times, I checked for dust and used the cloth as directed to remove any dust. The second attempt looked like it was going to work, no oily bubble, only to see the same results about 10 min later. Odd. But true. I had no idea that only the edges were sticky until I got curious after the second attempt failed and wondered how sticky that side actually is. I can't recommend this to anyone with an LG V20. I sent a message to the manufacturer, with no response yet.
