Product review (3 stars): vague instructions but good for most things
vague instructions but good for most things, but not if you want to cook longer than two hours, I do canning and this is what I bought it for,  if you get used to it, but does not work I bought a set along with this claim from both parties it would work, stovetop almost immediately gave error of overheatk, very disappointed at funds spent to be sure I could use this for making sauce etc, without heating up kitchen, and I cook my sauce on low for hours but miss having a gas stove for this, as elec makes it spit too much, even tried a diffuser which helped some on stove but not on this,
