Very good product for the price point offered… unit is all stainless steel and heavy ( I purchased the large sized ). I’ve only done one test burn and as it gets hotter, it will get the secondary burn through the vent holes at which point there is very little smoke. However I set the unit directly on the lawn and when all is said & done, it got hot enough to burn my grass. May try setting it on masonry bricks to see if that will help. Very pleased with the purchase. Only negative is it was slightly dented in two spots from damage during transit. Not sure if additional packaging would help as the large size is a beast. Overall: 5 stars to Ash & Ember
