I just got mine on Saturday. I definitely still have a problem with leakage (though I only used it for one day so far, got frustrated lol) Unfortunately I bought the medium sized one as well, and I'm still finding it difficult to pack such that it looks natural. But I think it's absolutely realistic looking, I just have to work at getting used to it, since I've been peeing the other way my whole life. I got the harness as well, and I can't really feel it all that much but it's the packer that I'm conscious of and I can't help but feel silly at times having the silicon in my pants.
@Potter: Do you have any tips on how to not get leakage? It seems like I have to always bring it way lower than I originally perceive.
