I absolutely love this cast cover. Super easy to use and shower with confidence.I spent three months in a cast and started with everyone's recommended trashbag. I did get the great idea to use saran wrap instead of tape and it was ok, but after the shower it was wet and messy. I read reviews on other items and saw things about how hard it was to put the covers on or that they broke after a couple uses. I didn't have any of that with this product.I wasn't sure what size to pick so I might have gone a bit larger than I needed but it worked out fine. The air pump makes it so that even if you do buy large it is suctioned to the right size - you just have a little extra material. It stretched easily over my cast and was easy to take off after.It was a little expensive, but worth every penny.
