worst experience with this product, due to poor quality parts used

two times hinges issues after replament again new issue with body fitting of lower body- not holding screw tightly due to thredings issue of body and result in gap, and loose fiiting causes making noise at opening and closing flap of laptop

how many times in a year we requesting service for such issues and waste time
