Holds a very consistent temperature, but the gap between the grease pan and the edge of the grill grate makes it easily prone to grease fires which ruin meals and are very dangerous. A wider grease pan, probably just elevate a bit more from its current position, would eliminate that end still allow for the airflow needed to create the polling smoke which allows for temperature consistency and even smoke distribution throughout the grill. Also, a larger grease pan should have a steeper pitch on it to ensure all grease flows to the trap. Liners would be more effective if they had a bit of a foldable wing to ensure the actual pan itself is completely covered, eliminating the need for extra foil around the edges. Great flavor, but a real design flaw in my opinion that could be easily fixed.
