this thing be a huge disappointment . after the initial silliness of play with it , it be not a practical device that anyone would use , and I do not know if anyone else have this problem but with two week the spring come loose inside and the whole thing literally fall apart in my hand . not worth the money -lrb- even as a joke -rrb- to buy something that fall apart so quickly . poorly make and customer service be horrible to deal with . the joke be on anyone who buy this . if you give they you money , that be you problem .
