We had been using another Boulder company for our networking needs but they changed their business model and coud no longer support us. So we were looking for a local business to help us with our new computer system installation. Our previous service company recommended iSupportU. After reading the only (three) reviews on yelp that weren’t filtered, we were very relucant to use iSupportU. We even tried to get additional recommendations. But in the end, we met with Shaun and after talking to him about his rotten yelp experience, decided to take a chance. We’re really glad that we did. The reviews that yelp considers “filtered” aren’t filtered at all. This is a fantastic company with superior service. They have fulfilled every part of their contract with us and all technicians that we have worked with and Christina in Mission Control have been excellent. We have zero complaints. If our review is filtered also, that will guarantee that something is broken at yelp (but not at iSupportU). Use them with confidence, in spite of yelp.
