The R2 Coffee Roaster gives you full control over the roasting process. You can adjust timing of the first and second crack, temperature, fan power, roasting time, and drum speed. Your profiles are stored in the cloud, so you can easily make changes and share them with others. This machine is compatible with iOS and Android devices.[where to get it]
