Query: Hibachi

I was surprised at the heavy duty construction of this product.Very well made and engineered.I have used this hibachi at tailgating parties and performs very well.The drop down door is useful for adding additional charcoal.The only drawback I can find with this procuct is the inability toraise or lower the cooking grate.But by adjusting the amount of charcoal compensations can be made.
