I bought this to play music from my iPhone through a mixer in my bedroom / home studio. Using it couldn't be simpler: hold the single button to initiate pairing, connect from the iPhone, and it immediately works. The pairing is remembered and it will automatically reconnect later. I also appreciate the inclusion of balanced audio outputs, especially at this price. The basic function of the device works very well.
Two minor downsides:
- I live in the UK, and the device only has an EU "wall wart"-type power supply without a replaceable cable. Thomann included an EU-UK mains adapter for free, but still, I would prefer either a replaceable cable on the PSU or a UK PSU. The DC input is an unusual voltage (5V, 2A) so i can't use a spare 9V PSU.
- The pairing button has a bright blue LED ring surrounding it which is permanently lit when it's paired. I wish that this could be turned off, or that it would use a smaller, less bright LED.
