To be honest i am in contact with quite a few FtM's and such devices are a godsend to them since it makes it easier for them to fit in with the men, able to go in a stall and pee while leaving the men in there oblivious to your gender, it is more awkward for urinals i believe, but the brand i most hear of is ManGo which is a popular brand or device ... i have no idea xD All i know is one of my friends was practically bouncing off the walls when hers/his arrived.

Other than transgender usage i can see the benefit at festivals or in situations where sitting to pee is just a nogo. That and certain European areas... holes in the floor are awkward to negociate xD

And the daunting 'how in the heck is this going to work' issue aside... one day would it be so bad to just see if you can? For some the squat and aim probably doesnt work... curiosity and the hygene reasons mentioned in the topic might let some females decide to use them ^^' camping seems to be the biggest motivator, who wants to risk squatting in poison ivy? im that ditzy sometimes you never know xD

** I double checked and ManGo is the name of a brand/ webservice that provides more solutions to problems that FtMs may stumble across in their day to lives, such as appearance and fitting in more with men. I wont provide a link but it is easy enough to find through google if you put in Man-Go at your own discression ^^**
