We needed a small and inconspicuous device to power monitors (computer screens) in a trade show booth.  This stick did the job nicely.It was hidden snuggly on the rear of the monitor out of sight and reach of visitors to the booth and did the job with out any hiccups.  It is smaller and cheaper than a tablet.  We haven't used it yet in any other contexts and probably won't so this is hardly a comprehensive review but we were happy with this solution.
