I got this 4 quart slow cooker to replace a larger Hamilton Beach slow cooker that I had for several years (I gave it to my daughter, it still works perfectly).
We recently moved to a house with a much smaller kitchen and this slow cooker is the perfect size. It doesn't require much storage space but is large enough to make a good sized meal or a batch of soup. 
Cleanup is easy. The crock and lid go right into the dishwasher. 
I do miss the digital control on my old slow cooker but I am very happy with this slow cooker and highly recommend it for a couple or small family.
