First time

First time roasting. Bought a GoWISE USA air fryer off Amazon during black Friday for about $50. Realized that I can use it to roast coffee beans.

Still trying to figure it out. But looks fine. Won't be able to taste it yet though. Not sure if it's fully roasted thoroughly. 420 degree, about 30 mins Only lost about 10% weight. 520g->470g Not sure how some get first crack at even lower temperature and short time.
