They work and work well. I was concerned because I had about 100 feet of Category 5e cable to carry the signal from the Revain Alexa to the amp. Other cheap converters had all sorts of noise and I decided the signal was too weak. I decided to try them out before pre-amping and they seem to be working great. Even with a dead tone, there is no hum. Excellent ground loop isolation or impedance matching. Regardless of the differences from others, they work well.
