Uncomfortable leg pad
Easy to assemble and adjust. BUT, cannot get brakes to actually lock when buttons are in lock position.  Have to be super careful.  The worst thing, though, is the knee pad. It is not soft, and has grooves in it, so it actually puts impressions on your knee.  An accessory knee pad is an absolute necessity.  I would return this, but it is the only way i have to get around at all, and of course, this is during shelter-at-home during the Corona virus.
