Query: Very Disappointed

I have used slow cookers for over 20 years, and this is the third one I have ever bought. I wanted a larger capacity and stainless steel look. I have never been able to use this cooker and leave the house. The food boils up at low (recommended cooking temperature) and steam spits everywhere. I'm back to using my old 15 year old Rival (smaller but totally reliable).
