Review title: confusing instruction manual
Product review: I was considering packing it back and returning after reading the attached manual. It states that no hard beans should be cooked in this pressure cooker. That was my reason for buying it. After some investigations I found that adding 1/4 cup of canola or other oil takes care of the foaming issue. It did the trick. It performed very well. I left beans in it for 3 or 4 hours to let them cool off. They were softest ever.Otherwise the device is very solidly built. It should manage many loads of beans and generate lasting pressure.
