Jack is the man! We had an iPhone 5s with a severely degraded battery(lasting maybe 8 hours max, on standby), but we needed the iPhone to last another few months before the«eligible upgrade» kicked in… Jack answered the phone immediately, came over to our house(by our request) super fast and installed a new battery in no time. He showed me the old«puffy» battery that had seen better days and we are now back in business. Will definitely call these guys again and recommend to friends/family in the area when(not if) they break their expensive gadgets. Very happy customer!
