Made by Matsushita Electric Industrial (now Panasonic) This was tested with two AA Ni-Cd batteries, and issued by pressing the red button in manual ("M") and auto ("A") modes. I haven't tested it with a camera because I don't have the environment to do so. Includes the strobe body, battery door, and dedicated pouch only. As this is a used item, returns are not accepted. Please consider this before purchasing.
