Pros
- The longest warranty in the class: 3 years, against 1 year on every other Masterbuilt model, and Masterbuilt pays shipping on warranty parts
- Reviewed, testing it: "When we set the temperature to 275°F, it stayed steady for the full hour it took to smoke the wings without fluctuating"
- The same 18 lb briquette hopper as the 600 and 1150 under the biggest cooking area, 1,260 sq in
Cons
- On Amazon only third-party sellers offer it (BBQ Island Inc held the buy box and four more sellers asked more, read 2026-10-17), and Masterbuilt voids the warranty for unauthorized dealers while publishing no list of who is authorized — buy from a retailer Masterbuilt names
- Reviewed found its grill surface "heats very unevenly", and starting on old coals left in the hopper "caused problems with igniting the coals"
- All 4 of its written critical Amazon reviews describe the controller failing, and its Amazon base is 8 ratings
The controller. Every written critical review describes it failing early, at a week or two months, or a unit that would not heat past 150°F, and slow parts: "The controller on mine died within a week though, and it took over a month to get a new one from masterbuilt."
