As much of a novelty as this is, it does just as handy for those late night in the woods "hikes" we all inevitably take when camping. One less thing to lose track of when you are most vulnerable, wondering what that noise was, and formulating an ridiculous plan to take out that bear, if it is a bear, before it can take you out. Distract it with the toilet paper! Genius. Bear antics aside, you can probably see the utility in this product, especially in the dark.
