It is nice and stable once you anchor it in.  It does take two people to put it together.  There is a lot of balancing frames to get it straight so 4 eyes work better.  It was missing one part so I called company and they put part in the mail quickly.  Shipping seems a little longer than normal 3 weeks but I had read this on another review so knew that.  I would rate it 4.5/5.0 stars
