BEWARE, TIs company replaced the battery in my Apple iPhone 5, for over $50.00 and when I arrived home the phone did not turn on again, I work the same hours as the shop is open, so when I had a chance to go back in they said they did not have time that day on few occasions, THEY DO NOT STAND BEHIND THE SERVICES GIVEN, BE AWARE!
