We've been using our grill for about five months now and are so happy to have made the switch from propane.  The unit is easy to assemble (much easier than a conventional gas grill), reliable, and easy to clean.  I am very happy with the support I've received from Z Grills; there was a small scratch on a surface (probably shipping damage), and they were more than happy to address the issue in a prompt manner.  I know that when I ultimately replace this grill, it will be with another Z Grills product.
