not right for every one
It was way to light weight for me to use.  We live in the country and it was unsteady and wouldn't go over gravel areas easily.  Other devices would maneuver better outside for me.  Even in the house from linoleum to carpeting I had difficulty going over the ridge between the two.  I am 5ft 11in female with Post-Polio muscle weakness therefore this device is not right for me.
