This place is awesome! Not only do they excel at simple repairs like replacing your cracked iPhone screen, they can also do advanced stuff like soldering! My 2009 MacBook was out of commission due to a motherboard connector I had accidentally knocked off during a repair, and they were able to solder a new one on within 30 minutes!
Basically, they saved my life and brought my computer back from the dead. It doesn't get much better than that.
