I received a product I had paid $400 for, that did not have a YKK zipper: the zipper was already compromised by the time I received it.

it caused me to look more closely at the materials and workmanship:

    * extremely cheap materials
    * messy workmanship

had the zipper been of decent quality, I probably wouldn't have looked as closely as I did and would be cursing how quickly it all fell apart.

in hindsight, it saved me some effort, as I was able to return, but it also turned me off forever on the brand.

a quality zipper matters, and if you don't have one, what else was skimped on?
