I just got done changing one out for a friend. PAIN IN THE BUTT. I got mine off of ebay, I wouldnt recommend getting one there. spend a few extra bucks and get an official nintendo brand top screen. The backlight for the off brand ones is kind of crappy. (barely noticeable pulsing, uneven towards the top of the screen)
PS: I typed the more offensive version of crappy and it was replaced with "multi-layered" who came up with that as the replacement in the word filter? That makes no sense!! haha.
