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.
***Update: 11/2014: It's been a year now and I still adore this little grill. I've got a kamado and 3 different kettles and this is by far the most convenient and easy to use. The smoke rings this guy puts on a brisket are amazing and the flavor is the perfect balance of wood flavor without overpowering the meat. I've researched about 15 different pellet grills and I still can't find a better value than what this grill offers
But as said, there are a few things we don’t like; it’s relatively small, doesn’t have a lot cooking space, and the design feels cramped. At the same time, it’s still relatively heavy at 140 lbs. For the same price, you could choose the Z-Grills Master 700D, which packs almost 25% more surface area on the rack. That doesn’t seem like much but is a significant amount of room. Or you could just spring for the Traeger Pro 22. There have also been reports of poor quality control, and that the temperature control is very inconsistent, often swinging up and down nearly 30 or 40 degrees.
When it comes to construction, few companies can beat Traeger. Its grills come with construction features like cast-iron grates with a clear and nontoxic coating that prevents food from sticking to the grill and fireboxes made from a similar material. Though Pit Boss grills feature similar elements, many look flimsy, and most will not keep up with your grilling and smoking demands.
Customer Service: I spoke with customer service department about 10 times during this process, and every time I emailed or called I received a different person in response to my same issue. This did not feel good as I never got past the ground level in service even asking for upper management. After the initial response to the dented barrel I received a month back order request for a replacement. After this no offer was made to remedy the situation meaning no refund, or any extras were given as a sorry. I had to contact 3 more times (with three different people) asking for upper management before they agreed on making up for the situation. I ended up receiving for "free" a folding front tray. A month and week later I received my replacement barrel only with no lid, and then a week and half later received the lid.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
