Two yrs ago we bought a knock off thinking we were saving money and real smart. Hated it, could barely get a fire going let alone the high temps we were told the Egg would do. LY we found the large egg in nest at Sam's and bought it. We've barely cooked on our gas grill since, by the time you pre heat it, the egg is up to temp and ready to go. Used it all winter, even. There's a learning curve, but we got a lot of information on the web. Love the flavor of charcoal, even adding hunks of apple wood sometimes. Between that and the masterbuilt smoker, we have lots of flavorful meals. The off brand found a new home when we set it out on the curb.
