Solid, but expensive
I like this stow bag a lot, but not enough to own a pair of them. Given the price, I purchased one of these, and one of the NRS stow floats (which I got on sale). The watershed bag is made of thicker material, the ziplock seal is beefier and easier to close shut. There's also a 3rd buckle. That said, there are some drawbacks to this one, the thicker material is a big rigid, making it a little harder to stuff in the stern than the NRS bag (or a typical dry bag). But I certainly trust this bag to keep everything dry, and I expect it will hold up to some abuse for many years to come.
