Query: Awful

A set of AA bateries will only power this thing for about 2 weeks...if it works. It's really messy. The battery compartment on mine was so cheaply made that I had to use some aluminum foil to get the batteries to make contact. Excess humidity in the air causes the food to clump which then blocks the food from coming out. I could go on but if you are still considering it at this point that's your fault.
