    Great! (if there is nothing wrong with it)

    We ordered two: tried the first one and the fan does not work. Still waiting to hear from Limelight customer service what they can do to remedy the situation. Fortunately the second one worked fine and our programmers had it up and running in a matter of minutes. Can't wait to use it in competition.
