Wonderful thing to have
It is a great little contraption. Pretty fool proof. As with anything dealing your spine, though, please be careful when you use this. Please read the directions. The only complaint, I wish the pulley system wasn't so difficult to pull and didn't jerk so much when you did. It really should be a bit smoother transition from inch to inch. Instead, I have to stand, pull it and guess if it's high or low enough then slowly sit.
