I was truly wanting this to be a winner and literally a game changer. Unfortunately, that isn’t happening. Instead this case has been a painful experience.Background...I bought this for COD mobile. Play on a iPhone and am a 2 finger (thumbs) player. My hope was the buttons would provide the same benefits as a 4 finger set up. I have found it incredibly awkward attempting 4 fingers play on the small screen of a phone.Pros...Slick technology. First class packaging and instruction. The product presentation was exceptional. The case is sturdy and feels quality. It also looks great.Cons...the glass has a significant negative effect the responsiveness of the phone’s touch screen. So while you gain 2 gaming buttons, the screen is less responsive. My game play initially significantly deteriorated. It took a few days to simply to relearn the controls with my new hud and gain new muscle memory. After that, I had to modify my game play to compensate for the touch screen. It took a couple weeks to get to the point where I felt like I was as effect with this case as I was playing 2 fingers. It was quite obvious the case would NOT offer all the benefits of traditional 4 finger hud. The glass comes with inherent frustration that has to be accepted if you are going to use this case. With that being said, I did start to make gains. Much of it was due to play style adjustments to minimize the impact of the cases limitations.The BIG CON...the biggest disappointment came a couple days ago. Now the buttons have become less responsive and are deteriorating. It’s awful!!!! I guess it makes sense. The buttons are mechanical.Bottom line...prior to a couple days ago, I would have said “buyer beware”. Now my strong recommendation is “DON’T DO IT!!!!” This purchase will lead to major disappointment. I stuck with it and went through the pain of adopting my play to this case all for the freaking case to not hold up. I’m not going to buy a new case every 2-3 months. Now I will have to go through the pain of unlearning my new game play and muscle memory. This really sucks!!!!The case was awesome The buns were extremely easy to assemble and the case is really good the only problems that I have is one I dropped it and one of the buttons started messing up and I have no replacement screen and They don’t have anymore in stock so I cannot replace the screen nor the buttons are so if you guys could figure that out that would be awesome
