Bottom line is, the lady J attachment is a good design, the urinal itself is basically a good design too. Drawbacks: you have to take the Lady J attachment off to close up the urinal and the urinal is not leak-proof. Am a bit disappointed. Working on remodeling it for convenient leakproof use.
We took this camping. The lid on the container does not screw on but snaps on, so it is not very secure. I think you could get the same use with a water bottle or other type container with a screw lid. We used it with the Lady J which was good.
