Previously, I had a round slow cooker that had no timer. I worked around the no timer issue but sometimes pot roasts got overcooked. And, last year I decided to cook a turkey breast in it for Thanksgiving but had to cut it in half because it wouldn't fit in the cooker otherwise. The Hamilton Beach 4 Quart Programmable Slow Cooker has solved both of those problems with it's oval shape and its timer. And, it's automatic switch to warming after the selected time is over makes sure my dinner remains ready to eat. 

This year for Thanksgiving I will be slow-cooking a turkey breast again and won't have to cut it in two this time since the Hamilton Beach 4 Quart Programmable Slow Cooker's oval shape will accomodate it easily.
