The size of this rice cooker is great, and it does a good job of cooking regular, long grain, wild, brown rice, etc. I've used it for oatmeal and wasn't impressed, but it did a good job on quinoa and barley.  All that said, it is kind of messy.  I've followed the directions to the letter, and it always splatters/spills over on my counters.  I just remedy that by laying out a tea towel underneath it to absorb any mess.  I also add a couple of extra tablespoons of water than is recommended since some of it spills out.  Despite the mess, I still like it.  It really cooks rice quickly, and cleanup is very easy.
