This slow cooker is amazing!  It's flexible in that I can preset the cooker on low only, or I can set it to cook for say 5 hours on low and then 3 hours on high, or simply to warm.  These are terrific features and I love my new slow cooker for all these great options.  I love the lock feature on the lid, keeps the heat in the cooker and allows me to carry out to another location.  I love this cooker! [This review was collected as part of a promotion.]
