I was going to buy the one lid to upgrade my ninja xl pressure cooker that I love love love, but glad I waited and purchased the speedi. I was intimated at first, but found it very easy to use. I tell my husband it is time to experiment and he rolls his eyes. Once my meal is done he loves it. Haven't had a fail meal yet. I must own just about every ninja product they have and they have made my life so much easier and a better cook.
