I bought this pressure canner specifically to cut my cooking time in the summer to keep the heat down inside my house.  The first thing I made was a batch of Garbanzo Beans/Chick Peas.  I followed the instructions exactly.  It was very easy to do.  The beans came out great and they tasted so fresh.  Next I made a pot roast.  Normally my pot roast takes 3 hours to cook.  Using the pressure cooker it only took 45 minutes of cooking time which is great for summer cooking.  I didn't care for the roast as much as my usual way of cooking it because it was a little tougher.  I'm not sure if that was because of the pressure cooker or because of the quality of the meat.  Either way I will do it again and just extend my cooking time.
