I have one. It is a very nice device. Basically converts your camera into a ambient light meter. A gentleman by the name of Wallace invented it. He passed away a couple of years ago. When I first bought my expo disc in the early 90s, I spoke to him at length about it. It will also allow you to check your in camera light meter and see how accurate it really is. Now some company owns the manufacturing. Great tool.
