Query: It sucks dont buy it

I bought this item and i thought it would work. It worked for 3 days and then it stopped working. When i called there customer service department i ask did i need a return authorization # and theys no. But there website states that they will not except any products back without a return authorization number. Now im afraid to send the product back without a return authorization number even though they said i didnt need one in order to recieve my money back. DONT BY THIS PRODUCT.
