This adapter greatly increased the range of my bluetooth connectivity and the signal remains quite stable at a greater distance. However there are 2 side effects I noticed:
1) Network connection in Windows always appears as "disconnected" (while remaining functional). This is due to the Personal Area Network (which I don't use). Annoying, but no impact
2) The adapter seems to interfere with other adapters when they are close ( 50cm). When I use my smartphone with bluetooth next to the adapter I get microcuts in audio streamed via bluetooth. Side effect happens with this device, connected to both a Moto model XT1635-02 and a Bose Q35 (serie 1)
Overall still a good buy, however bit overpriced considering the side-effects.
Great range and easily configurable. I mean really easy. I plugged it into a Pi and a Win 10 machine and it was immediately recognized and started throwing devices into the stack. Couldn't ask for more than that.
