You can only fill 2/3 of this 4 quart pressure cooker so you cannot really do any canning unless using very teeny tiny jars and cooking very small portion of food.  I have a 5 quart pressure cook and you cannot put a whole chicken in it. You need at least a 6 to 8 quart cooker to cook a decent meal with meat and vegetables.  I won't recommend buying this pot even if it is cheap.
