Ten roasts back to back in two and quarter hours, no fuss whatsoever. I love this roaster!

Indeed it's a great roaster!

Molly kindly sent me the specs of the blower, I think it's a good information to owners:

I imagine the heat gun with low air flow (around 150 l/min) being a problem only if one keeps the blower at minimal flow, but probably at 5 or more it gives more flow and pressure that the heat gun, hence the good results from Rafael, with a nice heat transfer and no flow problem through the drum.

Looks like roughly ten times the airflow at the same static pressure. Not sure how much of that air is for the gas flame itself, and not for the drum. But even if its 50% or 75%, it means there's still plenty more ventilation to create a higher heat flux with lowered ETs
