2 stars for the quality of repair and level of customer service.
I've used UbreakIfix before but there wasn't one in the area I work so I tried Mac Masters for my repair. I have to give the nod to UbreakIfix as although slightly more money, their fixes always work. My phone came back from Mac Masters only partially repaired. When I went back in to advise of the continuing issue, they just blew me off saying it must be a software issue and didn't even look at it.
End game, you seem to get what you pay for and I won't be back to Mac Masters.
Mac Masters - If you feel inclined to provide me even minimal customer service and actually take a look at my phone, please do contact me. ajnelson13@me.com.
If you don't care to improve your customer service, just keep doing what you're doing.

I received a very gracious and helpful email from the management at Mac Masters. Based on how kind and caring the manager was in the email, I've upgraded the rating from a 2 to a 4.
