I wanted to write to tell you how grateful I am to the Surgeon that designed this wonderful waterproof protection. My 31 year old son injured his knee pretty bad in a dirt bike accident and I didn't know how we were going to survive getting through this long process of him having a cast and not being able to shower. I knew that this would never happen and he had threatened many times to remove the cast and I would get very upset wondering how we would get through this period of time. That's when I found this Dry Pro and it has been a blessing. My son was able to take his daily shower without getting his cast wet and it worked wonderfully. Thank you so much for making a very bad situation easier to cope with. This surgeon deserves PRAISE beyond words.
