Totally unusable on a plane.  Maybe because I'm taller, 5'9".
I was looking forward to trying this out on our flights.  I found it to be totally unusable.  There's not enough room in an a regular airplane seat for my legs, much less trying to hang something from the tray table.  On the flight that was had exit row seats, there was nowhere to hang it.  So it's worthless to me.  Wish I could return it, but I waited too long to try it out.
