I am a retired Mechanical Engineer... I admire the AA canners for their ingenuity of making a canner that has no rubber seal. The lid is precicely machined to fit the pot and only a thin film of olive oil is needed occasionally to assist putting the lid on. The Wing nut type clamps (yes clamps is what they are called) Are situated to evently distribute the force for clamping down the lid. Like an Autoclave for sterilizing medical instruments. If you take a look at the lid on a presto the lips that bring the seal down are placed in the same orientation. To evenly distribute the counter force for the pressure.I also wondered about the AA compared to the Presto canners, and noticed the many locks on the AA gadget. Can you call a pot costing $250ish a 'gadget'?
Consumer Reports doesn't review them either.
I bought Lodge cast iron and enameled cast iron rather than the $$$ French brand, as it was rated second, and it all works great, especially given the cost differential.
So, anyone have issues with Presto canners? I pitched my mom's, given it's very great age, so a new one would have to appear if I actually want to pressure can.

I have no issues with a Presto canner... They work the same way. the advantages are they are lighter and can be easier to use. The gasket does need to be changed out occasionally so inspections of the gasket is important.
But they all need to be inspected and made sure everything is in working order... Instructions come with all caners. Care and use and when to replace things.
