My wife had the first opportunity to use the Little John Portable Urinal this past weekend when we were camping. The temps hit below 15 degrees and we were confined to our shelter. Not wanting to go outside to fight the elements she used the urinal and it worked worked just as advertised! It should be noted that she used the "Lady J" female adapter and it was well worth getting if you are a woman.
This worked great on a recent trip with several couples who had to camp in close quarters - going outside late at night would have disturbed everyone, so this came in really handy. And it works just as advertised!
