Why did I wait the 4 years it's been on my wish list?! My mom used the old fashioned kind while I was growing up, the kind without the newer safety feature of the handle interlock that keeps you from opening the cooker before the pressure drops. The jiggler on top is different now, it only allows 15 pounds of pressure rather than the 3 settings mom could use, but it's doing the job. I've done pork chops, beef barley soup, Greek stifado, venison stew, and others in the first couple weeks I've owned this and the time it saves is awesome. I no longer have to start meat cooking at 1 pm for dinner at 5.
