I can pee standing up on my own, thanks you very much, but it might be useful for those who don't want to touch themselves or use their pelvic muscles. For passing reasons from an FtM point-of-view, as long as you present as a man, men in men's restrooms don't notice if they don't see one, or they think you've got a really tiny one... they just can't imagine one can pee standing without something phallic, but if you pee through a plastic thingy they might notice. If you intend to use it because you wear clothing that does not allow you to pee without undressing, then it's not gonna help because you will not be able to position it correctly, find pants with a longer zippers or something.
I think breast forms and binders would be more important.
