I bought this about 10 years ago, but I haven't used it much. I stored it after using it a few times, so there's no discoloration. There are some small scratches. It can perform complex movements, so I haven't been able to confirm if it can do all of them, but it moves forward and backward, sideways, and its eyes light up. It makes a sound when started. I checked the operation with batteries. Sometimes the response feels a little slow, but I don't know if that's the original specification. I don't have the instructions, so I don't know. Please understand and consider purchasing. I removed the batteries from both the remote control and the main unit.
