My office uses this business whenever we're having a problem with our computer system. We always find that their staff are highly competent in their work and always do a thorough job. It's a little bit hard to understand their IT language... but they can usually word it so we can understand it.
With minor problems that occur on a regular basis with our server, their staff teach us how we can resolve these problems without having to call a rep out, or are always happy to walk us through over the phone.

Great business =)
