Query: total dissappointment

I bought these hats - one for my son and one for a couple of Seniors in college so that they could have a little fun with their friends.I had spent a Christmas in England with family and had a blast which is why i bought two to use here.I was so dismayed when neither of them worked.I think I was sent seconds. What are the chances of ordering two hats and both of them not working. There was no manufacturer note inside the box with directions -nothing in fact except for the parts. I tried to find the company on line - nothing there either:-)Whatever you do - DONT buy one unless you can see that it works first.
