What I really appreciate is the well thought out reply's you get from VF. Nothing makes me more mad than to have a propblem with something, then you email the manufacturer about it, and they send you some pregenerated message back that is absolutely no help at all. The same message must cover a 1000 different problems, and not actually help with a single one of them. VectorFlight has always replied to all my questions with well thought out responses, and they take a genuine interest in what their customers have to say.
