Query: Beware of defective zippers

I am on my second Classic Tour Bag the first being replaced under warranty just before the warranty ran out. The rear U-shaped zipper (rear) came apart on the right side rendering the bag pretty useless unless you like your stuff falling out the back onto the road. Kuraykyn put me through the wringer too as if I was too hard on the zipper - told me to "zip slowly next time". The replacement did the exact same thing after only 6 months. Other than the defective zippers on this model, I love the product design and all the features. Only wish it was durable. If you ride once a year, you'll probably never experience what I have. If you ride everyday like me, this bag won't hold up for your needs.
