FULLY FUNCTIONAL. 9/10 Works perfectly, with the exception of an occasional short in the volume knob which can cause the left speaker connection to "short out" to a lower volume. This only occurs when moving the volume knob around below the 25% vol region. When it does happen, the signal is fairly easily returned to normal by slightly repositioning the vol knob, even just tapping it. If your workflow allows you to generally keep your interface volume above that 25% range, you should be able to work free from having to deal with the shorting issue, generally speaking. All other functions work as intended. Front and back panels still have the manufacturer's clear protective sticker attached which can be easily removed.
