It's been 6 months since we purchased our Artisan 6M. We (and our customers) couldn't be happier. The roaster runs like a champ and it's easy to operate and maintain. We can change the roast profile to match any bean we purchase and get consistent quality results. I love the hands on approach, the ability to watch the beans the entire time they're roasting and the chaff removal system is amazing, it produces the cleanest coffee we've ever bagged.
