This basically all worked on my Mid-2012 MacBook Pro - so that was good. And the general appearance and fit matched my old part.However, there were two flaws: (a) there are 4 tabs on the side to hold screws, one was bent and had to be bent back into place. (b) there was a collection of about 15 pixels near one corner that did not work properly. It's not so visible against a picture, but visible against other backgrounds. Not a huge deal, but not perfect.
