This shell is very pretty, flexible, easy to implement but not very well cut in the power supply. Maybe it's the boss of the calibrated model is wrong? IN any case, it protects the laptop well and really prevents pets to the most requested places (corner phone for example). The screen son is not easy to put on and always has an air bubble at the end of such, so there must be a greater film quality to be top of the protection. But then when you see the price, you can do it.
