High quality for it's price.
Solid aluminium chassis, internal electronics well designed. I've still not measured the output power, but since it's built on a TPA3116 Class-D amplifier IC there is no mystery as the datasheet gives this information. Good lowpass filter at the outputs. Very low noise (if none), and performs well as a large screen TV-amplifier with 24V power supply and 2 x 10" PA-speakers. One of the best eBay products I've seen so far.
