BBQ Genius Stainless Steel Smoker Box

Having seen one of these in a restaurant, I fancied smoking some butter and cheese myself at home. On arrival however, the tin was much smaller than I was expecting for the price and too small to smoke anything of worthwhile size. it might fit a small blob of butter with the woodchips, but probably not the hay as well. Frankly it isn't the size I had imagined by looking at the picture.
