Received this about 2 weeks ago. Have only been using it a week. I installed the natural gas conversion kit myself. Very straightforward and you don't need a gas fitter as the instructions indicate. Overall, I am happy with the quality. Natural gas is a cooler burning gas than propane but still gives off a good amount of heat. The red volcanic rock is enough to fill the basin but you could use a little more to level it off. Don't overfill or the cover won't settle on top properly. Easy to use/ignite and a nice addition to our backyard.  Of note: we used the nylon cover during rain but you should remove it and wipe it down after a rainfall. We will be installing a wood or plastic corrugate topper and then installing the nylon cover when storing it during the winter in Vancouver. If you are in colder climates during the winter, try and and store it inside to prevent peeling of the exterior coating.
