Stand Alone (part two)

This video was posted on Facebook today and I thought I'd share it in reference to a previous post. If I can manage to squirrel away the $77.00 I may still get this...but I'm still on the fence about it. I will say that this very brief video is pretty convincing. I'd love to hear what others think about this or if anyone has used one yet (and thanks again to those who offered comments and insights on the previous post on this subject).
