I go there all the time as I'm always seeming to need something or have some question about how to maximize the usage of my phone. Jeff runs a great shop he is the manager. Then there is Tommy who's a wonderful well-versed salesperson, Daniel who has been there for quite a while and always treats me like gold, as well as all the other people they always make you feel good and are super helpful.
Highly recommended. Even if you are not a T-Mobile customer and have questions they will help you it's that kind of a place.
