High quality components, includes a printed out schematic but the overview is in Chinese. Works well and sounds nice - good as an external amplifier for TV for example. You can replace the TDA2030a for LM1875T for better sound quality if you wish, but obviously you need to buy that separately. Just make sure you understand how to power it - +12V, -12V from a center tapped transformer, you can for example use a transformer with dual secondary wirings. Just don't get confused by the schematic and don't plug your usual one pair of AC secondary and a ground cable in the middle - this will result with a small explosion and a number of bodge wires afterwards. Don't ask how I know - just solder when sober.
