The West Bend Crockery Cooker has been many places with me!  I have used it for single serving cooking on up to feeding a whole houseful.  It is very easy to use, just throw the ingredients in and select the heat setting.  I love using it for stews and soups in the fall and winter especially.

I don't especially like the design, as it is a little old fashion for my tastes.  The interior cooking portion removes nicely for ease of cleaning, but fits together nicely for storage, moving and use.  The top can be a little difficult to keep clean and occasionally there's a bit of residue remaining...
