up on the top tool

With the back cover itself I was very pleased. High-quality workmanship and everything fits. But what I found disappointing was that's no use the tool part. Suction cup and the blue lever tools for cutting the connections on the board you can use without any problems. However, the screwdrivers are much too large for really small screws in the iPhone. That's why I had to buy a screwdriver me even more.

What you definitely need is time and a lot of patience and even a small tip. Does best after the Mainboard photos or marks is out where that screw should go. These qualities are different for each hole and if you do not know in the end where the screw which belongs, the assembly will be very annoying.
