I opened the package only late because I have not had the opportunity before, when I discovered that the layer and split, and the metal plate was peeled off, I have not even tried to change it on my laptop, having exceeded the period of one month for the return, I will stay with this defective product, but one thing is sure I will never recommend to the seller, and strongly recommend to do so. FYI I'm not going to take into consideration the negative reviews thought they were acting fussy about, I had been wrong. go your way
