Our band received 4 pcs of this set only a few days before COVID-19 quarantine, so unfortunately we were not able to test it live on stage...
...but we did it in our 2.5 by 3.5 metres concrete made basement rehearsal room – a place where average radio equipment would fail. These mikes did not.
Selecting 4 different channels from the same frequency group went easy and voila, all 4 units worked flawlessly. No dropouts, no feedback, nothing, despite of the fact that they all were within these few square metres.
Just for fun we went into the sauna on the other side of the concrete wall and still had no issues.
We believe that it will work even better on stages. Hopefully we will see after the quarantine.
