This Grill is awesome.  Although I had a faulty controller and a damaged barrel when I received the item. Z-Grills was quick to send me out a new controller and even shipped me a new barrel along with 3 20lb bags of Oak pellets to make sure I was happy.  I have owned the grill for about 2 months now and after I installed the new controller its been smooth sailing.  Temps stay well within the range z-grills states they will and my BBQ comes out fantastic.
