I know you're disappointed in the Topeak right now and you might even be questioning your decision to buy it, but trust me, this isn't a deal-breaker! If you bought from Amazon, they will probably ship you a new one and pay the shipping for the return. If not, hopefully the company that sold it to you will handle the return just as professionally. They really should have noticed a bum zipper before shipping the item!
