Much to say there is not to the product actually. There are departures due to the workmanship: On my copy, the socket for the power supply has been well soldered wrong on the hidden in the device circuit board, so that when the plug is inserted in the device this angle is plugged. Overall, but that does not so trusting impression on me. Despite the low price, I would not buy it again. Since it but otherwise works as it should (Dolby Digital, etc. is properly changed) and anyway disappear in the closet, I'll keep it and forgive 3 stars for the previously flawless operation.
