Well, now I know how many watts my amp is putting out, how much voltage is going there, and how much box rise im getting.
Im very satisfied with this device! –

The difference with term pro lab magnum and this BHG-WM is about 200watts. And this reading depends on the range of watts it has to read. Like the lower the reading, the higher the accuracy.

The concept is awesome but the material was vinyl plastic 3d printed material which when mounted, the vibration from Bass caused unit to blick on an off with pause, then cracked an split at mounting feet . Sadly disappointed..
