I would give the cooker five stars, but the manual is lacking. It has really only safety instructions and those are somewhat oddly translated into English. Since there is an intimidation factor for those of us new to these devices, a better manual would be a huge benefit. However, some of the electric pressure cooker cookbooks have some great "how to use" information and that has been very helpful. My experience actually using cooker has been excellent. So far I like it, and I like what I have cooked with it. Rice is outstanding cooked in it, and hard boiled eggs are very easy to peel.
