Used this within a week of receiving! We are still trying to learn how to utilize it best but the design is perfect for slow and coal flavor infusing cooking. Extremely happy with this purchase. Additionally, I ended up ditching the bottom metal rack to hold coal above the pan (for ash collecting purpose). Having that rack made the coal too close to my food; I was afraid of burning my food. So i laid the burning coal directly on the metal bottom of the grill and it was fine. No burnt food and the metal bottom held out against the coal well.
