One size does not fit all
Too large for me.  I'm an average sized male (5'11", 180 lbs) and the straps are so long that I cannot reach far enough to get the straps velcroed.  There is some noticable effect at the point I can reach but then the Velcro comes loose.  I believe I'm following the instructions but they're not easy to see. Returning to find a smaller model.
