I have a Timberline 850 which replaced an old Traeger BBQ 100 and a Genesis gas grill. It is my main go to for everything.
Pros:
Good even heat across the whole unit. I don't have any real hot or cold spots. Although I did not test it fully against my remote probe.
It will get to 500 and stay there. but it does take time. I use grill grates for searing.
Good pellet consumption.
Works pretty well in cold weather. Did chicken at 350 when it was below freezing. Wind does not affect it too much.
I like the APP I can sit on the couch and control the unit while watching the Bears lose.
No bad temp swings, runs usually within 5 degrees. temp does drop a lot when you open it up.
I do a lot of overnight smokes with no issues yet. (knock on wood)
Cons:
Front shelf is kind of useless.
only one food probe and it seems off from my Maverick instant read. maybe 5 degrees. Not sure which one is off. I need to test.
Have to clean it a lot. like every 20 hours of use.
Grease trap set up is funky. I've had a couple grease fires when I do high heat and don't clean it first. Only a few and not major.
No direct sear design as on some other units. You would think on a total redesign they would have it.
Not made in US
Oh, Super smoke setting is questionable. I only use it for reverse sear steaks. The problem seems to be unclean burning of pellets do to the fan cycling completely off for a second or two. This can cause sooting issues. This is not an issue for me because I do long smokes at 250 anyway. Maybe this can be fixed in the future by a firmware update.
Do need to realize that it is a direct auger feed and can cause burn back into the auger tube. When I cook at high temps, I back it down in increments before starting the shutdown phase. No problems for me.
My finalists were the timberline or Blazn. Loved Memphis, but could not justify price. Timberline only won out because I saw one at a dealer by my work and put it in the SUV that day. No buyers remorse for me. Very happy with it and I love to cook on it. Ribs, Brisket, Shoulder, Turkey, burgers, steak, chops.
Please ask questions or raise any concerns and I will answer as objectively as I can. I'm not a cheerleader for Traeger. There are so many good brands out there now! When I started Traeger was the only pellet grill.
I hope this helps!
