Very impressive! We are using this system for live sports from an outfield camera. No more long cable runs!!! No glitches, solid signal!

### ⭐⭐⭐⭐⭐ This is a great piece of kit
*by A***R on March 29, 2025*

Despite the video latency if that is a factor for you then probably look at another brand but if it isn’t this is a very excellent piece of kit. I do production sound so latency was not at all an issue for me. It’s like the Shure Axient of Wireless video transmission, changing frequencies when disrupted.
