I like the system, but the belt sizing is a bit hard to determine for a snug fit. Also the elastic nature of the belt, which is necessary for a snug, dry fit, does wear out with constant use.

I had to order a new belt for my shower guard. It's a bit confusing knowing the correct size to order, especially since you have to wrap it around back to the front to make sure you have a dry fit. I measure 39 inches at the stoma and ordered a large, but it was too short. When I explained my problem, they sent me a small one to add to the large and together it works great. Customer service is excellent.

Repeat customer. Some improvements have been made since last one which is great. Best product for purpose I have found
