I purchased these bags about 6-9 months ago. At first, I really liked them, especially the fact that they had a mechanism for holding them together once folded without needing a pouch that may get lost. I discarded the small sack meant to store both bags almost immediately because it was too easy to lose. Just recently, though, holes have begun to form along the bottom seams of the bag. I plan to re-sew the seams for reinforcement, but another probem is that the seams along the top of the bag are unfinished, so loose, very thin strands of thread get everywhere and stick to food containers with condensation on the outside. Also, the handles are sewn together at the top instead of being made of one piece of fabric, which makes them weaker. Mine are pulling apart, and again I'll have to sew these together. Given what these bags sell for, that seems unacceptable to me. I have a flip and tumble bag, too, and although those are pricey, they are much better constructed, so I would consider buying those.
