I received this item at the end of last year as a dead stock item, practically unused. I roasted about 5 batches over the New Year's holiday. While I haven't confirmed all operations, the basic functions work without issue, and I was able to roast evenly. This is an early model, so temperature adjustments are not possible. You control the roast by managing the amount of beans, the timing of their introduction, and the timing of their discharge. The automatic discharge timer can be set, but it's only a guide. Temperature display is available, but its accuracy is unknown. It's a 100V model, Japanese specification. The instruction manual is in English, and the original box is included. The box will be used for shipping, with the shipping label attached directly to it. Both the exterior and interior are clean, but I will give it a quick cleaning before shipping.
