When not perfect, I feel the ash box. This is slightly narrower than the column, so always trickles past some ashes and you then have to sweep the walk. Due to the large heat development, the funnel has now also been discolored neatly at the bottom. This must be well but take in stainless steel in conjunction with fire and embers in purchasing.
All in all, a good and nice barbecue, which is highly recommended at this price.
