My son has the same model and I was impressed while sitting around the fire pit one night. Due to that experience I ordered a fire pit. However, I was not impressed with the very thin steel wall of the pit.  I had to remove one of the grill supports and reposition the support. This action enlarged the screw hole and rendered the a tight fit for the screw impossible.  I am going to use a nut, bolt and washer as a corrective measure.
