Masterbuilt Gravity Series 1050 Digital Charcoal Grill + Smoker
The most cooking area for the money, with a manifold to watch — A 1,050 sq in gravity-fed charcoal smoker, 225–700°F, with the deepest Amazon owner base in the class (3.8★ across 873). Its critical reviews add a second failure to the electronics one: heat manifolds rusting through in about a year, even under a cover, and Masterbuilt's warranty excludes rust.
