A transparent chamber makes it easy to observe the beans during roasting, and the chaff collector makes cleanup a lot less messy.
New to this model is a range of extra heat and speed options that really elevate it to a new level. There are nine levels for both, allowing curious roasters to control the process with a lot of precision. It also offers real-time temperature readings from inside the chamber.
The only real downside is its relatively small size: a 4oz capacity will need pretty regular roasts to meet the needs of a coffee-loving household.
