I actually went to their new location at 4207 N. Scottsdale Road (Scottsdale, AZ 85251). It is in a very strange location, positioned in a small room behind a small boutique clothing store. You either have to walk through the boutique store or drive around the back to find the back entrance. The important thing is that they have a commercial presence and regular store hours. Many of the folks in the cell-phone repair business work out of their apartment or some other sketchy arrangement. I felt very comfortable walking in to this business office because the location is fantastic (very close to my home and in the heart of Old Scottsdale) and they used professional invoice forms unlike many other repair places that work on a "cash only" and a handshake basis. They obviously saw the advantages of having a business storefront, but they don't want to waste precious funds on unnecessary overhead, like a large building.
Enough about the storefront, let's discuss the service. Mel, the tech on duty, was extremely friendly and professional. We had some problems fixing the screen of my phone, but it turns out it was an issue with my phone - not the screen. This was verified by another independent source. Mel was completely upfront about the service, the cost of the service, the expected wait time, what he could do and what he could not do, and the likely outcome of the repair.
I was extremely happy with the outcome of my transaction. This is a small operation in a very small location, but the service is top-notch. Mel was honest and completely trustworthy. I would definitely return, and I would send anybody I know to utilize his services if they are having cell phone issues that are not covered by a warranty or insurance.
