Very bad experience, I took a Xiaomi Mi Max to repair a screen change repair they put a screen crap and there were light leaks by the lower buttons, they told me it was original Xiaomi, they did not repair the light leak and the screen was better than the previous one but it is not original, at home we have three identical phones and when you put it with the other two the quality of the screen is much lower.
