I ordered (perhaps another account) this kit to be able to change the battery of an iPhone 4S imminent death. The job of this kit is well done! The small orange base, may seem mysterious, but lets put the iPhone on it and not to lose any micro-screws that could go astray very quickly after unscrewing. But even better, the tips magnetized screwdrivers allow for precision work. I had another screwdriver, but they were quite damaged. Those seem to be rather solid. They will also be very useful to open my macbook pro, screws being the same. The rubber grip allows good adhesion to the tools.
Also, they allow to unscrew the inner screw of the iphone, it's quite nice.
The only regret is that orange plastic thing, which makes the spatula lever. She spoils very quickly.
In short, I intend to keep these long screwdriver!
