Just an FYI sportsstuff is bankrupt and another company bought all their inventory. They will not honor the warranties on the products. We bought a tube off ebay on 4-20-10, it popped a seam and couldn't patch it. We called sportsstuff for a replacement when we were told about them and the bankruptcy. We are lucky the seller on ebay is going to refund us and take it back as they do not have that tube anymore. Be careful when purchasing a sportsstuff product.
