You can't hate on this bag too much, because of the price. That being said, the zipper feels pretty cheap, and I wouldn't expect this thing to last forever, especially if you zip/unzip a lot. The rest of the bag's materials feel adequate, and the stitching and construction is totally passable. The nylon straps and fabric aren't robust, and this bag would not last in a hard use application (sliding in the back of a work truck, sharp tools inside would both make holes quick). I've turned mine into an emergency car kit, and this bag worked perfectly. I was able to bet a lot of stuff to fit in the bag. Since the bag is for emergencies, I won't have to use the zipper that much, and it should last. Even if the zipper did completely fail, the bag's opening is made so that not much would fall out, as long as the bag isn't moving. The side pocket zipper is the same as the main zipper. Final thought, this is a good bag for storage, look elsewhere if you want a quality bag for daily use.
