The backpack was used one time and the zippers broke. I contacted Amazon to exchange the item and found that you made the whole process very simple and accomodating. Kudos to Amazon. You sent a replacement backpack right away and when it arrived I used the packaging and provided shipping label to return the backpack. You even acknowledged receipt of the package. Good job. My only hope is the backpack doesn't have problems in the future with the zipper. It seems to be rather cheap, as in a plastic zipper not metal to hold up. Tenba is a major manufacture of photographic backpacks and I assumed they have a quality product. I'm keeping my finger crossed. I'll continue to buy with confidence from Amazon. Thanks.
