well, this really is quite a cool little clock.
If you want to know what the time is in the nite, slap it on the head and the lights come on..just be warned that it is bright and youll see little floaty things after it beams in your eyes !
But its very stylish and fun, get it you wont be at all disapointed!
It takes 4x AA batterys, but will run on just one! (as i think the other three are used for the lights)
