What to know before you buy

Largest pouch: Pouches seal across their full width only when they are narrower than the 10.2 in sealing width; we leave half an inch of margin, so 9.7 in is the widest pouch we would pair with it.
Chamber: The usable chamber is 10.4 in × 12.9 in × 5.1 in: tall enough for bone-in cuts and jars that have to clear a closed lid.
Upkeep: An oil pump needs its oil changed on the schedule in its manual, so budget for pump oil alongside the machine.
