Fake Gas Burners

[Chipchopper]

recently I saw a tv program highlighting the sale of fake goods and the dangers that can happen by using them. One person who was a victim of a fake, portable, butane, gas burner, had horrific burn is injuries to his face and hands, when the device literally blew up in his face.
To bring awareness and clamp down on this kind of crime, how can the general public tell the fake goods from the real thing ?.
