But we wanted to leave some information about the roaster on the web page for those who still own this model. The roast profile seems more like a convective process to me than a hot air popcorn popper based on the results. Bean agitation has been orchestrated by dissimilar vent sizes and an eccentricly centered rotation in the bottom plate of the roast chamber. They mean it. I roasted 4 oz.
Roasts are even and consistent, from bean to bean and roast to roast.
Be aware that this model does not vary the airflow like the newer Precision, so it is more like an electric air popcorn popper, with the addition of a timer and a cool cycle. It's easy to operate and clean. You can alter roast times by simply turning the timing dial mid-roast. There's a 2 minute cooling cycle built in. Total full city roast time including cooling seems to be 8 minutes.
