Well built and nicely concealed when the lid is closed. The bricks around does the work on keeping the heat/temperature.
The compartment just under the bricks I thought it was a storage is useless when you are cooking - the temperature is so high that anything stored in there will melt.
The gridle doesn't go all the way up because the leveler touches the frame on the side... I guess that's an engineering design issue.
In my humble experience as a longtime brazilian bbq cook - the depth could be increased actually by adding the NON-storage space depths - that would be perfect depths for cooking.
