We have had a couple of these fail at the office, they just make a spark and then trip the power as soon as you plug more than 1 thing in it.... i asked the bosses to stop going to game or makro to buy these cheap as plugs....
I keep hoping someone will do a sale on the "dangerous" multi-plugs from Ellies. I'll buy several. I am fairly certain we'll manage to not put plugs in upside down or with one pin in the next socket.
