so far, it's a piece of junk.  Opened the box and it appears we got someone else's return.  Wires not connected, stabilizer (yellow) bar not connected.  The power box for the chair is literally zip tied in a bundle of wires and hanging, not attached to the frame, screws look as if it was ripped from the frame.  There's a red ribbon tied around the round base of the chair.  What the heck?!  And of course, it's Friday so we'll wait the entire weekend and probably until Tuesday for a reply from the company.  Unfortunately, we ordered two of these.  One delivered today (Friday) the other not coming until Monday.  So disappointed.  Unfortunately, I had to give it 1 star in order to post this review.
