I've used pressure cookers for many years including some of those very expensive models.  This is one of the best cookers I've ever owed.  This cooker is constructed of high quality stainless steel and is very easy to use.  Pressure cookers are very safe. If you follow a few simple rules, you'll never have a problem.  I use my cooker weekly for everything from cream of potato soup to braised lamb shanks with wine sauce.  Additionally, it is amazingly cheap to own. My only con: wish it was made in the USA, otherwise, highly recommend.
