There are signs of liquid leakage, but all items powered on and functioned. Only one sound source function of the Kaiser Pointer could be confirmed. It seems there's a function where the pointer lights up, as shown in the last image, but I couldn't figure out how to do it. This function is unconfirmed. Other than that, I believe they generally work fine. There are minor scratches, etc. Everything shown in the images is included. Please confirm before purchasing.
