Very bulky, heavy part with 1.5mm wall thickness and 2mm edge - ie in practice use with a minimum of 4 natural coals in chimney pipe nearby and a full 15 minutes. Anrauchdauer to the Kaminaufsitz the heat transfer to the tobacco. Even the head (Saphire Power Bowl) you have to pretty much fill with tobacco case. Who does not long has patience, can the essay only with windshield operate (disadvantage: then tends to overheat and the tobacco flavor goes flutes). I turned 0.6mm wall thickness and surface sunk the holes with chamfers. This is a smoke as with other heads with three natural coals and less tobacco is possible. Anrauchdauer is now about 8 min. and is acceptable. I've been using the I smoke most of all needed for my sapphire head a Kaminaufstz without the adaptations carried out, I would have to top retour sent and otherwise would have remained at the front building with Mod and aluminum foil.
