Small Chefmate microwave (Pittsford)

Small Chefmate microwave --600 watt. It does have a small chip in the paint inside--see photo. Chipped area about 3/8 inch by 1/8 inch. The paint chipped when I was scrubbing down the inside. Manufactured in 2006, so it is an older machine. Someone gave it to me and I do not use microwaves, so I cannot guarantee it works. Size 10.5 inches high, 12 inches deep, 18 inches long.
