Have used it. Find it great with no problems to date.
Originally suggested to me by a family member working with a major internet security company where he and many of the top staff also use it. Seems as good a reference as it can get so gave me confidence in it.
used it loads of times - fantastic, set jobs going in the morning before I go to work, when in work login - start new jobs (video conversions etc) and when jobs done I can shut the pc down remotely as well. Class.
