Dropped my phone off because the home screen wasn't unlocking. They quoted me 79.99 over the phone in case it was the digitizer.
I get a call not too long after that it's working just fine, and that it actually fixed itself. They told me no charge and bring it back for repair in case problem persists and/or if it happens again.
They could've easily charged me the original quoted price. Instead, they were honest and forthright, and wouldn't even let me tip the technician. This is the way you build a business and its reputation. They will have always have my business, and i'll recommend them to all my friends/co workers who is in need of a repair.
