I worked as advertised. Does a super job on small batch pressure canning. It’s four pint gem jars or six smaller jelly jars. Very easy. You only have to switch the valve to closed after its pressure released for 10 minutes. Then it does it’s thing and turns off on it supposed to. Super easy. I haven’t used it for anything else yet but it’s going to be a great all-around appliance for the cabin. I can fish and this is why I bought it.
