Query: Great Product!

I purchased two. One for a gas and one for my REAL (yes charcoal) grill.This cast iron smoker box blows away the foil packs and the thin stainless steel smoker boxes commonly seen in the big box stores.Heats evenly, provides good smoke, essentially no maintenance or setup, and heavy duty to last a life time.
