Good product overall
Overall, I'm quite happy with my purchase. I'm very happy with the fact that it's immediately detected by win 10, no driver problems, no need to fight with it, which is very pleasant. The only downside is that the range is not as good as expected from the documentation.
With a usb extension cable and a bit of tape to keep the dongle away from the ground plane, I can communicate reliably with my amp at 3m, but it's still a bit of a fiddle that I wouldn't have minded.
