I've heard lots of good things about Traeger grills and was excited to get the Pro Series 575 Pellet Grill. The first four times I used the unit, it worked great. However, on the fifth time, the unit would not keep the temperature anywhere near the setting (set at 165 but with actual temperature at 365). The unit would not respond to adjustment. I made call to Traeger's customer-service number, which was a good experience as I spoke to a live agent who helped me troubleshoot the unit. The agent stated that the controller was bad and that they would send me a new one to replace it. As of this writing, I have not received the part so time will tell if the unit works properly after I finally receive it and install it.
