Presto has been around for years and I had one in the way back but was a bit afraid to use a pressure cooker.  Now...many years later....I bought a new Presto and I don't know why I was ever nervous.  This one is so simple and the instructions could not be more clear.  I especially wanted it to cook dried beans.  Not only are they much cheaper than canned beans they actually taste better.  I cannot recommend this product highly enough!  I trust Presto because of their longevity (I can remember when they were pretty much the only game in town) and because they are priced competitively.  Have no fear......!
