You are worried about flare-ups: When grilling fatty types of meat on a propane grill, you run the risk of having flare-ups, where the flame gets too high and too hot, burning the meat. You have to keep a close eye on the propane grill to guard against them. But with the Traeger grilling system, the even distribution of the heat and the indirect heating system prevent this problem.
I have a Traeger Texas 34 Grill I purchased in January. It worked well for a short stint (1 or 2 sessions) and now will not get to the desired heating temperature, above 400. I have called Traeger and they have sent me multiple parts (2 new controllers/probes/fans) to replace in it, on my own time. Still not working. Upon calling them they said they could not send me a new grill because I purchased from Amazon. They said I needed to contact them. A $900 investment is essentially useless now. DO NOT BUY THIS PRODUCT.
Bought Junior Elite 20 pellet grill at Costco special sales event. Took it home and it simply wouldn't get up to temperature to ignite the pellets. Auger made extremely loud noises and then simply refused to operate. Packed it back up and returned to Costco with no problem. They had no inventory so I called Traeger. Woman on phone was very pleasant and helpful. Asked if I could get Traeger to simply replace the grill at the same price I purchased it for. Her supervisor said no and if I wanted it for that price I would have to drive to another state and purchase it at one of their event presentations. Made no sense to me why they would sell it to someone else for the "event" price but not to me who had already done. Poor customer support and silly supervisor. I will look elsewhere.
