Dead simple to use, I didn't read any manuals. Good, reliable signal. The only downside is that the receiver generates some background noise. There's some audiable hiss from the receiver plugged into the audio interface even when the transmitter is turned off and disconnected from the mic. The noise is very obvious in headphones (DT 770 Pro), so I was on edge whether to try to ignore it or return the item for a refund. However, I'm glad that I tried connecting it to the speakers (Yamaha HS8) and there the hiss is virtually non-existent, plus HS8 have some of their own inherent noise (when your ear is right next to them), so it's not really that clear which noise I was hearing, and from two meters away it's inaudiable. In the end, I think it's a great item for the price.
