Kaleido
M6S Dual System
$2,199 current direct reference- Best fit
- Mid-capacity prosumer micro-roasting
- Tradeoff
- Its attractive capacity-to-price ratio must be weighed against seller support, probe behavior, smoke extraction and the difference between maximum and routine charge
02premium
Aillio
Bullet R2
$4,099 current direct- Best fit
- One-kilogram prosumer drum roasting
- Tradeoff
- One-kilogram capacity does not equal one-kilogram repeatable light-roast performance in every room, and smoke handling, cooling and cleaning remain operator work

Owner experience
What repeats after the purchase
Owner discussion repeatedly returns to radiant profile behavior, cleaning depth and external cooling rather than specifications alone.
These are self-reported experiences from a changing mix of owners, conditions and software versions. They identify questions to test, not a failure rate.SignalWhat owners reportOur readEvidence
Radiant profile behavior, cleaning depth and external cooling
Owners repeatedly return to smoke and chaff, electrical supply, sensor behavior, profile transfer, back-to-back recovery, cleaning access, app continuity, parts, support and whether stated capacity is a useful routine batch.
Roast and cool a full batch with the intended smoke control before judging the tidy machine footprint.
