The Bialetti moka pots are different, although they look similar. They are heated on the stove-top, and water moves from the bottom chamber, through the grounds, to the top chamber under pressure.
The drip-o-lator style pots are NOT heated on the stove-top (a separate kettle is used), and the water moves from the top chamber, through the grounds, to the bottom chamber via gravity.
