A Chinese product is in my view very possibly, even probably, perfectly satisfactory in every way, to suggest/hint that just because it is Chinese it is not is rather low. The other point is that a two pin plug is perfectly proper - but arguably not for someone who prefers (perhaps simply for reasons of local practicalities) the abominable UK three pin plug (it is what the sockets are designed for, unfortunately, so one is stuck). A perfectly functional solution is an adaptor (easily obtainable), else replace the plug with a UK plug. Its earth terminal/pin will not serve any purpose at all - quite acceptable and normal, there are plenty items sold and in circulation in the UK with "false"-earth-pinned plugs (the pin is made of plastic).
