if you have an electric coil or gas stove you're good. if it's a glass top it won't work.
A glass top stove works just fine. We've done a bunch of them on one.
I've never owned one but everywhere I've read and heard they don't work because of the way the elements heat and they don't stay consistent. good to know they can work. I stand corrected.
Having had 2 glass stop stoves, I hate the things but they do work just fine with a pressure canner. They also work fine with a water bath canner for canning other stuff.
