was looking at a relatives house where there was a child and i explained to them about this fatally flawed campaign, yet they insisted they were more protective. they then told me to try and take them off and it really did take a load of force to pull it out, much more then a child would be able to do anyways.
If they take more force to remove than that exerted to remove a normal plug top then what damage are they doing to the socket these things are quite prone to breaking and leaving pins in the socket and IMO the tighter they are the more likely this is to happen leaving the socket in a dangerous condition
