The PRO 780 Is my 4th Traeger (I still have and use all 4). The new D2 technology is really a game changer. At first when they came out last March I was like ok that's pretty cool but do I really need that in a grill? Well I can't tell you how awesome it is to be able to get home from work, fire up the grill and monitor my cook while I'm walking the dogs. I mean I'm literally mind blow that I get a push notification that my grill has preheated. It sounds over kill but it really does make a difference and fits my busy lifestyle. Not to mention the the grill is stout. Its sturdy, looks amazing and it has been re-engineered to be more quiet and efficient. You can control the thermostat in 5 degree increments as well. Guys, if your thinking about upgrading or adding a new grill to your arsenal. Do it. You wont regret the new D2 grills and your grill confidence will only rise! Way to go Traeger!
