I know that there are many thread about this but i wanna some filtered feedback about Mozo back covers. I wanna buy one for my 950 xl because it makes the phone look even better and because of that creaky sound (a lot) that annoys me (a lot). These cases are not cheap so I wanna know how are they holding up. Are the material really good? They resolve that creaky problem? Are they resisting well to daily use? If you have many cases what is the best? I like a lot that cyan color case, anyone ave any problem with this one?
