It works well. When I put my paddle down for stability the leash hangs in the water but when wet it doesn't spray or flail water from moving around when I start paddling again. It can stretch a bit longer due to the elastic in the green cloth when needed and retracts without issue. The Velcro seems to hold when wet and I like the security of knowing my paddle isn't going to far when I stop to enjoy the scenery or take a picture. I use a lot of products from Seattle Sports and have been happy with the quality of their products.
I recommend having a paddle leash
