I live in a remote community and I unlock iPods as a side thing. A lot of people started asking me about fixing screens, so after making an order with ifixit, this iPhone 5c was the first device that came through my door.
The repair went fantastically. The tools I received from ifixit were exactly what I needed to make the repair. The iSclack works exactly as described, and the various hand tools made the job smooth. The repair guide was also exceptional and turned out to be very helpful.
Use a soft surface around your work station in case you drop your screws! I spent twenty minutes looking for an errant Pentalobe that could have been saved had I been more careful. Also, allow extra time for stubborn fasteners - you can't work out a #00 screw the same way you could on your back deck. Be patient or you'll strip your screws.
