Works as it should. Unfortunately, the board is processed so bad that to be ashamed of as the manufacturer! In light wiggle the cord can hear only mono! The box is filled with hot glue, so you need to get to the contacts first remove all the botch. Then you can see quickly where the problem is the pin to which the cable is soldered to the black channel. Is completely loose! If you build the board, one can reach the soldering and resolder. After usefully attach a strain relief.
Unlike other recessions I have to say that the RCA plugs are OK, the problem is definitely the unattached PIN.
Only recommended if you like tinkering. As a manufacturer, I would be ashamed to sell something under my name. Too bad that is still set to the laziness of the buyer 14 items to send back.
