This is the best Halloween mask...My Son Loved it and My Niece also. The cord and the battery pack was so light weight you would forget you have it on. The lights wre just right, didn't have to worry about them getting eye fatigue or headaches at the end of the nigh, because after they finished with it, I wore it to a Halloween rave! I was the hit of the party. No one could find them any where and I had mines. I really had a ball showing off this mask. The lights and the functions got 5 stars, the material of the mask got 5 stars, one feature of this mask that will always be overlooked is the foam where the forehead goes keeps the mask stable, stops restlessness, eye fatigue and more, made the mask feel so good on...I would recommend this item to family and friends and anyone looking to purchase an excellent quality item. Fun and Cool!
