i got this for 45 bucks so i am very happy considering it sold for 110. there is a timer setting that you set numbered 1-15 but it does not correspond to time in minutes. you have to listen for second crack as well as watch the color of the beans as you might not hear second crack with all the noise the machine makes. the cooling cycle starts at the "3" setting so if you think you need a longer time to roast move the timer dial before it hits 3. the machine does an excellent job of collection of the chaff from the beans and cooling down the beans.it takes about 10 minutes from start to finish (beginning of second crack roast). smoke level is no worse than that you get from popping popcorn.
received the roaster along with the grinder within the week of ordering
Three Month Followup
600 batches done with the roaster still going strong (100lbs of coffee) tip. clean air vents on underside of base periodically to prevent decrease in air flow of fan.also tighten tabs on pot if it becomes loose fitting by bending the tabs upwards to maintain proper seal between pot and base of machine
