Got this to set the full horizontal plane for my camera and it works great. I checked this in both X and Y with my electronic spirit level and it turned out to be accurate. This allows you to visually set the full level within 0.1-0.2 degrees, which is more than adequate for photographic use. The bubble is easy to see and the markings are clear. The aluminum ring is well made and provides good weight on the flat.
