Query: It should be no star!!!

I bought this item in 2004. It has been in my car since then. Package unopened. Now, I had to jump my car last week. Opened this package. The product did not work. Tried several times with multiple cars. No use. Its just a junk. I was so happy I had this with me for emergency. But,its useless. Finally my roadside assistance saved me :). Stay away from this product.
