I purchased these to protect my ear from water so I would be able to shower after having ear surgery. I can say without a doubt that this product kept my ear 100% dry. I placed a small piece of cotton in my ear with the ear cover over my ear and took a hot shower. I was able to wash my hair, face and body & rinse thoroughly. After getting out of the shower and removing the ear cover, the cotton ball was 100% dry each time. I was so impressed with this product that I shared it with my doctor, and he will be sharing it with his patients after he tries it for himself. His nurse has seen this material, and says they use it in the hospital, but never used for this particular purpose. She didn't realize it was for sale in this form and she is going to try it too. Needless to say, I was so happy to have this product this time. This was the 2nd procedure and the products I purchased for the 1st procedure failed me. I would have had to wait three weeks to take a proper shower if I didn't find this product because I wasn't allowed to get my ear wet. I'm sure I'll find other uses for the remaining product.
