What to know before buying

Listing details to confirm

Listing details conflict on power: one field says no batteries are required, while another says two included C batteries are required. The stated block size of 2 cm x 2 cm also differs from the customer summary's description of pieces just over 1/2 inch square, and the listed dimensions of 3.94 x 0.79 x 0.04 inches are difficult to reconcile with a cube. Confirm the selected listing's details and included battery configuration.
