Picked up my Traeger Pro 780 this afternoon. Assembly was a breeze and the unit fit and finish is solid. The temperature here was hovering around freezing all day. The LCD display doesn't like cold temperatures and was a bit hard to read. I did discover if I looked down at the display instead of head-on I had no trouble reading it. I didn't get into connecting it to my wifi. The priming and initial burn-in was no problem. I seasoned up a package of split wings and put those on and they turned out well.
No complaints so far, but I've hardly put it through its paces yet.
