Which is pretty much why I've owned one but never used it...
What I keep thinking (and I'll admit - I didn't make it to the end of that video) is - okay, I've peed in/through it successfully - now what? I'm going to want to clean it. I'm going to have to put it in a pocket. I probably don't want to have it in the same pocket as my trail snacks ...
But then, I am not to be trusted with innovative female sanitary devices. I tried a Diva Cup for a while, and then somehow - really I don't know how this happened - managed to drop it when it was full and spill blood all over the carpet (this was back when we had carpet in the master bath, which is ridiculous and gross even if you don't make a habit of spilling blood on it). I can only imagine similar clumsiness with a FUD.
