A couple of years ago I bought a WMF pressure cooker. I have always had problems with it losing steam through the gasket in the lid, so I decided to replace it with a Kuhn Rikon. It looks good, is not too heavy, but the main thing is that it is completely steam tight. I have seen many pressure cookers over the years and they all leak some steam but this one is the exception. It means that it is totally quiet and you finish cooking with exactly the same volume of liquid as you started. A remarkable performance.
