Just adding my experience with the Yoozon. After seeing many posts about issues with this and even other protectors having problems in the corners, I wanted to make sure I did mine right. I followed instructions to the letter and even swiped for an extra couple minutes with my own microfiber cloth. I installed straight on the very first time (luck or skill I'll take it either way). Then the horror, the left corner wasn't sticking just as I had seen photos about the right corner. I held it down with my thumb for about one minute and that easily fixed the problem. So, now it looks perfect in all corners and I have no complaints. In fact, it was much easier to put on than the Zagg I had on my old phone.
Two things to add from other comments I've seen. I don't know who thought that this protector was not plastic and that it wouldn't bend. If I wanted to add actual glass as one poster thought that the Yoozon was, I would have gotten the Droid Turbo 2. Not quite sure what people are thinking these things are made of. For me, make it durable and just do what it purports to do, not protect it from every unreasonable scenario. Also, in response to another poster regarding how it fits with a case on. I am using the Ringke Fusion, as well as the RedShield slim. The screen protector does not interfere with either case. Hope this helps.
