Unless you have child size feet, this is difficult to use. Too low to ground. Width fro end to end is too narrow and does not all for any other position of feet other than straight forward and close together. Bar itself is so narrow, it is difficult to get proper positioning below your feet. Nonskid surface peels off as your shoe basically slips off edge as bar is so narrow, but not far to fall as it is so low to ground you can't get much ankle flex before the heel of your shoe hits the floor. Needs redesign! Powersystems team....have you ever used this, sitting or standing?
