Corvus torches for kids

I bought two of these little Corvus LED dynamo torches for my 3,5 year old twins the other day. What we love about these little torches: 
a) small and light, they fit perfectly in little hands 
b) powered by a recharchargeable battery that is charged by using the crank handle. No need to fume when the kids leave them around without switching them off and the kids love to turn the crank handle round and round to recharge the batteries when the light starts to fade.. 
c) and seems this is (at least for the time being) the perfect weapon to fight off any ghosts that might be lurking around.
