I purchased a screen replacement for my 2015, 15" MacBook Pro, and the part arrived very quickly. The screen works like a charm; however, iFixit coated the screen with an aluminum paint in order to cover any scratches it may have had in the past. This would be fine if the screen I purchased wasn't classified as an "A" part. I'm sorry, but if you have to coat an entire screen to hide scratches before selling it, then that screen is definitely not a premium part. The only reason I didn't send it back is because the screen works, and the warranty is too good to pass up.
