We connected our new fire pit to our natural gas lines and it is magnificent!  Delivery was first rate, all internal parts easily accessible for simple install. We opted to use glass chips versus the lava rocks that come with the system.  We have been using the fire pit since new year’s eve and it has functioned flawlessly.  It comes with a cover which fits snuggly. The wind screen was a separate purchase which fit perfectly with the existing opening.  I would buy again!
