Query: great for on the road or just to keep around for emergency.

These are great, I keep them in the truck all the time just in case. You never know when one might come in useful. Whether hunting, long trips where someone just cannot hold it any longer or even just for someone who's lazy. The gel absorbs all the liquid and the smell, so you can keep it around if needed. Compact and easy to use and since it's unisex you don't have to worry about your lady friends. Great simple product.
