This is my first 4 qt pressure cooker. I love its size, perfect for cooking smaller portions. It sets up pressure much faster than my 6 qt, ( which is also SS).  I love this pressure cooker, the lid goes right on easy and locks down easy, its sturdy, make sure your husband or man person in your life tightens all of the screws on it as they loosen after one use. I canned up some meat in this one and it was completely perfect after being under pressure for 15 mins timed.  I'm definetly gonna get another one of these.
