Honestly shame on the owner for trying to make me feel guilty for wanting the original new charger I just paid $85 for.

I found this place on Yelp, sent a message, within a less than a minute, I got a quoted price, what time to come in and roughly how long it would take. No BS, no "we'll have to see what condition the phone is in, in order to give you the price", just exact price right on the spot. I came in at the exact appointment time, and to my surprise Jerry, the manager was there waiting for me. Dropped off the phone to him, he told me to come back in 30-45 minutes. He didn't give me any paper or receipt, so I felt a bit worried since there was no proof I left it with him but I did so anyways. Came back 45 minutes later and there was Jerry waiting for me again, showed me the phone and it was a brand new screen, worked even better than before and i was out the door in a few minutes. One of the best experiences I've ever had with repair service and definitely making this my new go to place for any repairs. I also found out Jerry not only does Phone repairs but also, tablet, and computer so I'll be coming here for those in the future. 5 stars for awesome experience here, and another 5 stars for Jerry for being friendly, easy to deal with and just providing good customer service.
