What to know before you buy

Largest pouch: The maker states a maximum pouch size of 16 x 18 in. Buy pouches no wider than that, and remember the chamber has to hold whatever is inside the pouch too.
Chamber: The usable chamber is 16.75 in × 18 in × 7 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.
