Review: Excellent product - This is easy to use and very effective. I had to keep post surgical sites on my leg dry, and taping a garbage bag every night wasn't high on my list. This cover goes on easily and keeps your leg completely dry. Very worthwhile purchase.
Review: It is affordable and effective. Caution is required. - My wife broke her foot. She wears a hard cast from her toes to her knee. It's bulky and a miserable ordeal. If you get it wet in the shower, be prepared to go back to your orthopedist/podiatrist and have the cast cut off and replaced. Who has time for than nonsense? Keep the cast dry! Want to shower? Do not try using a garbage bag with a rubber band; it will leak if used as a stand alone solution. Your cast will rub on the bag and on the floor and water will find a way in from above or from below. My solution was to cover my wife's leg with a garbage bag and then to use this disposable reusable cover for double coverage. The garbage bag prevents the hard cast from tearing/abrasion of this cover. Each cover lasts through 6-8 showers but will eventually leak due to tears or stretching the leg opening. You get two in a pack and the plastic is thin but is actually effective at keeping water out. The stretchy opening allows you to fit it over the cast and pull it up over your knee. As I said before, the garbage bag helps to prolong the life of this cover. Don't spend too long in the shower as the thigh opening is stretchy but does fit snugly around your thigh and does restrict blood flow - but it is also tight enough to keep out water. After all, it is all about keeping the cast dry.

I wasn't sure about this product that my aunt recommended, but cover worked out awesome and no leakage. Great product and easy to use. I put the cover directly over my walking boot post surgery and worked great.
