Great so far. I’m on Android, so I can start with a recipe from Ikawa and then tweak temperature and fan profiles as needed. Ikawa includes a sampler pack with the roaster, and none really blew me away, at least with the recipes provided, so I started buying bags from another green bean vendor closer to me. I prefer light medium so usually stop shortly after first crack. But I’m still trying to learn how to use rate of rise, and lower slower development to get different flavors from the same beans.
