belated and smallish review: it's excellent for packing, but be careful if you're wearing it to sleep because mine's shifted shape a tad (i believe due to the position i sleep in). this isn't a big deal for me but i figured i'd mention it. briefs are best to pack with, as alex has said, but i'm still a boxer-briefs man through and through and (provided they're not loose) they work just about as well to hold the ezp in place. i use it as an actual stp pretty sporadically, but managed success at a urinal for the first time ever and couldn't be more thrilled about that. mine doesn't empty out quite as quickly as i'd like, but i pee pretty fast, so this is kind of user-error on my part. i wound up clipping a small bit of the urinary meatus to help, but i'm still struggling to let myself go slower and wind up doing a stop-and-start kind of thing. i've found that if i'm not careful about it, a little bit of urine does trickle across the middle of the rear edge, but i've not had a full-on "accident" with it (to the point where i needed a change of clothing or a shower or anything) since my very first use. it's got a great learning curve, holds itself very nicely in place in a tightish pair of boxer-briefs and even better in briefs--to the point that i'll actually willingly wear briefs, which previous to having the ezp would be unfathomable. i will say peeing with it is definitely easier with briefs (part of the reason i use it sporadically for that purpose) but as someone who's been fairly unable to use any other stp, this thing is a godsend. i wish it were a little cheaper so that it were more easily available, honestly, because... it's just brilliant. utterly wonderful. my only complaint is specific to my own situation (that i pee too fast), and while i hesitate to call anything perfect, the ezp is pretty dang close. very highly recommended, if it's within your budget--and if not, sign up for alex's mailing list anyway, 'cause he sometimes does giveaways and you might get lucky.
