Extremely Positive.
C-Man & Boyz Audio did an amazing job with an alarm install in my car. C-Man answered all my questions, even stayed a "bit" later than closing so I could get there to pay the tab (my wallet didn't like it of course, but I digress).
They even got to display just how much they care about customers.

A little bit of miscommunication and a part was left out, but C-Man went out of his way to get that missing part for me. Definitely worth the money!
