As far as I can tell, it works well. However, don't be fooled by the "bypass" claim. Although it switches from broadcasting from a wired device (external speakers) to a Bluetooth device, it does NOT allow both. Either one or the other. Guilty. In one or two places where this was presented in the list I was either misled or misunderstood. Assuming the list was written by the same people as the instructions which (English version) are awful, I'll stick with my three star rating.
