Query: Buy a duffle instead

We've been through three of these for the two Radian seats we own. Not one of them has has lasted more than two uses before a seam rips or a zipper breaks. The fit is impossibly tight and if you don't get the seat in perfectly, the zipper will not close without breaking. I finally bought a couple of $12 duffels at Target which did the job and look much sturdier. To quote another reviewer, "Nice idea... terrible quality".
