I have used this one for 4 years, super useful to have it, even sometimes it can serve as a DI/jack-xlr adapter. Endurability is not the best,I now have issues with the mute button. Sometimes when using the mute button, the right channel speakers stays muted and doesn't come back on. Now I mute it using the volume buttom. Perhaps some spray could help, but also thinking about switching to a new one that includes multiple inputs and outputs.
