Zipper problem on all bags

Received and used and almost immediately a zipper pull came right off. Sent back and received 2 new bags. After a couple of uses another zipper pull came off! I wasn't man handling the zippers, just using them. The bag does keep cold things cold as opposed to just room air. In that respect it does what is advertised and I'm happy with that aspect of it's performance. That's what earned 2 stars. Having the zippers fall apart is what cost 3 stars. Can't recommend.
