The boning in the canopy is not supporting it properly when it is opened (or being used) however it still works, it just flops down on one side a bit. I believe it is an individual issue and probably not commonplace among these. I can easily fix it by replacing the boning. Other than that, It works great, fits my car seat (which wasn't one of the ones listed) and has a nice thick feel to it. The material is quality. I'm happy with the purchase.
