This LED Purge mask is really very cool! It lights up and looks awesome in the dark. I thought it would be hard to see out of while it was lit, but that was not the case. It is easy to use, easy to wear and i can see out of it, not to mention it is pretty darn awesome! I am going to have a lot of fun with this! There are three different modes to the lights, stay on all the time, flash on and off slowly, Flash on and off fast or just plain off. it is easy to figure out and you can put the remote in a pocket or clip it to your clothes. The mask itself is lightweight and very good quality.
