Assembly instructions has unreadable small images, one can only guess where that screw should go. Many parts have been delivered bent flap does not close evenly. Metal edges are very sharp provided with metal shavings. Attention build! The cleaning is difficult, it is possible that carbon from large cooking chamber only with NEM small whisk broom sweep out across the stage front, which then pollute heavily. Barbecue itself ok, something is always lost steam over the oblique lid.
