I have a Bullet. I've learned to like it more over time.
There are several positive attributes:
Footprint
Fully inclusive (roast thru cooling)
Can be used stand alone or with computer monitoring
Capacity
Longevity (so far anyway)
Pretty decent repeatability
Easy to get basic roasts
Con's
Electric/induction heating isn't constant source heat: it cycles making it a different process than gas.
Personally, I think it's pretty little hard to get refined roasts
There is some weirdness between their IR temp and their probe temps
Chaff build up in the roast chamber during the roast can be an issue
Folks think that their roast world community and roast sharing will/can lead to identical roasts. It doesn't work that way because there are too many variables. They might be similar but they won't be the same.
Like I said, I'm learning to like it more over time. I may have different requirements than others though. Like I said, it's easy to use to get large, decent roasts.
I think everyone is right on three mentioned in the past, Artisan, Huky. Or the Bullet, however need more information on the Bullet, havent seen much feedback on the Bullet.
