My 6002b lasted about one year. It made phenomenal turkeys, pork shoulder, tuna steaks, and turkey burgers. 

Then the fire rod stopped getting hot. They sent me a new one, I had to swap it out. That didn't work, so they had me do some diagnostics and send a video. They sent me a replacement controller. I swapped it out. Now it gives me heat errors after I turn it on following the startup procedure in the manual. It also does not maintain temperature. 

They're sending me a new hopper assembly, which I get to install when it gets here and hopefully that fixes it. If it doesn't fix it, I'll probably buy a Traeger. 

If it works it's great, but don't expect more than a year out of it, and get ready to watch videos of grill repairs... kind of like this one.
