This is a Cuisinart kitchen scale I purchased at Macy's in the US. Size: (Measured at the base) Approximately 18.5cm in diameter (Measured on the surface) Approximately 14cm in diameter Condition: Purchased about 3 or 4 years ago. There are no noticeable scratches or stains. However, the buttons (the part you press) are originally a bit stiff. Sometimes it doesn't turn ON with one press. Also, it seems to be not very good at measuring 1g or 2g. It currently works without any problems. (Since it is an electrical appliance, I cannot provide a warranty.) It's a kitchen scale with a few quirks. It runs on batteries. Please understand if there are any oversights.
