Alex did a great job replacing the battery on my iPhone 6 Plus.
I called and emailed 3 other places and Alex had the lowest price for this service, plus he provided in-house repair, so I didn't have to travel to a store and wait.
He was extremely friendly and polite when inside my home, and we had a conversation the entire time he was repairing my phone.
The total time of him repairing my phone, and paying for it probability took 15min. Bundle this with the fact that he had the lowest price and made house calls, using him for any iPhone repair is a no brainer.
I would definitely recommend Alex for any phone repair, and I will be using him again.
