This is almost the same back glass as the original. The only thing you should know is that there's a sticker on the lens that is hard to see and some people here think that their lens are scratch but they're wrong. Great and fast shipping!
I just got my backplate and it worked perfectly. It looked brand new with absolutely no scratches. The camera lens is very clear and scratch free. It came with the pentalobe screwdriver that you need... I wish I knew this because I had ordered one separately.
For the people who say that they had a scratched lens... I wonder if they didn't remove the plastic protector. It is not noticeable and it looks scratched before it's removed.
