It does what it is supposed to do gracefully as both transmiter and receiver - once charged and setup (in no time, really) - are ready to go and are both squirrel-sized. No rack to carry with!
Very good built quality, range in excess of 40 metres (outdoors, low background RF nosie, TX and RX need to see each other), perfectly usable for measurements (this is what I use it for), have not tested it with any music/speech signal though.
Quite low latency, receiver provides microphone level output, XLR connectors are very decent to say the least.
3 hrs of operation time seems realistic, I therefore like this little toy set a lot.
Easy recommendation.
