I have 2 presto 16 1 presto 23. They range in age from 50 to 5 years. All work perfectly. I have 3 AAs. I like them but they are a pain on the ass to get the lid on even. If the lid is not even it will leak steam like crazy.
I agree it depends on whos canning I don’t mind fussing with American , girlfriend only uses presto electric it makes all the guesswork gone. I tell people if you really ding Americans lip bad it wont seal. I use American for big jobs 14 quarts makes it faster i use a camp chief propane outside
I canned 3 -14 quart batches of green beans it still has propane. You don’t have to get small ones all those places sell 60 pd tanks too twice as large as typical grill tank thats all im buying now. You should have more then one if you can i have several i store them in building away from house. But these tanks are proven safe millions of them across usa
