Tippy and not comfortable
I found it not helpful at home, too tippy if you have to make a tight turn, and not as maneuverable as I expected.  LOTS os backing up.  Would work well in wide open spaces and going out and about.  But it's heavy to lift in/out of the car.  Also, there is a hard ridge running side to side on the pad.  Couldn't find where to kneel - in front of it?  On it? Behind it?  Can't see what the purpose is.  It hurt no matter what so I padded it with sheep skin which I strapped on.  That worked but it need attention as it would slip out of position.  I had ankle surgery and if I didn't place my knee far forward, the foot dangled which was not recommended.
