This product was a bit difficult to screw on.  The product had a plastic part which the screw needs to screw into to connect the rod and metal stand, however the plastic component was not stationary making it tough to screw the parts together.  However, after several attempts, I was able to screw in all the rods and it is very stable.  It is a sturdy organizer and keeps all my paper off my desk.  I would recommend this.
