4.5 Design fault makes this absolute rubbish Mayhemfollows | 09/08/2007 | See all Mayhemfollows's reviews (1) I purchased one of these for my son and he used it five minutes before it stopped working. Changed batteries and it still didn't work. I asked a friend who just happens to be electronic expert to look at it and he said "this will never work for any length of time as the LED light is not powerful enough to take the power going to the light". He changed the led and sure enough five minutes of use and the light was burnt out. I am sure there are many unhappy childern out there.
