Very bad
I bought this device as a second try after LJM analogy ( same as audiophonics with same SA9023 chip that stoped to work), they both had same problem: stop streaming randomly or after switching next song, I need to conect and disconect usb more than 10 times !!! and simply at the end stoped to work, they stoped download driver to computer. Please note this was not my laptop problem because it works with many other usb audio device very good.
