This item has been sitting in storage for a long time. I inserted batteries to check its functionality, and only confirmed that the screen lights up. I have no knowledge of this product, so I'm not even sure if the product name is correct. Please make your judgment based on the photos. Although I confirmed the screen lights up, I haven't performed any operations. I felt that the battery fit on one side was a little loose. As this is an old item, I'm listing it as junk. Batteries are not included.
