What to know before you buy

Largest pouch: The maker states a maximum pouch size of 12 x 14 in (30 x 35 cm). Buy pouches no wider than that, and remember the chamber has to hold whatever is inside the pouch too.
Upkeep: An oil pump needs its oil changed on the schedule in its manual, so budget for pump oil alongside the machine.
