Does exactly what you think it does. I just wish the connector parts were darker so it could blend in more.

  • Bass watt metering is close to expectation Bass watt metering is close to expectation
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.
