i have a suspicion that the chinese company are OEM's for known brand appliances, having said this, it is no surprise that they come up with such offerings...
even the FLUKE dmm's there are models coming out of lazada and you can almost swear it was a fluke except that it had a funny name...
take our own Dai-Ichi speaker manufacturer, who OEM's products for name brands sold outside the country....who is to prevent them after they have acquired the technology and knowledge to make their own using their own labels? how sure are you that the speakers that you brag about are not made by Dai-Ichi?
