I've been wanting one of these masks for a long time now as they look so cool. The mask cane well protected and I just had to insert two AA batteries in to the compartment the out the mask in and adjust it to my head which was very easy to do and is a very comfort fit, the mask itself is lightweight and once switched on looks absolutely fantastic when in the dark my 5 year old son loves it too and now wants his own so I'm going to buy another one.
