I just got my EZP that I ordered recently. I got it a few days ago, so I've had time to test it out some but still need to practice some more to familiarise myself with it. But so far... I love it. It works great as an stp for me, although requires for me to fiddle a bit to position it due to my thighs being a bit bigger than the website recommends (can't quite make a 5cm/2inch gap in a wide stance), but that takes 5 sec and then it goes well and I don't spill at all. However the only way I can position it places it a little too high up so the shaft points slightly upwards, but I manage that by simply bending it downwards slightly while holding it. So that's not a big issue either, as long as I remember it.
First couple of times I used it naked, but now I can use it while clothed as well. I haven't used it in public yet, cause I simply haven't been in public yet and it's not often that I am. What I'm working on with the stp now is mostly increasing my confidence with it, working on relaxing enough to go (shy bladder), and controlling my stream cause it sometimes sprays if I don't focus on not making it so. But all of those things get better and better. I've only used it 3-4 times so far though, and didn't stp much at all before then. So I'm a fast-learning beginner. I previously only tried to use the Mr. Fenis stp maybe 2-3 times over several years, but it was a hopelessly bad stp for me. The EZP is a so much better.
As far as looks go, I'm a very light-skinned white guy with olive undertone and I got the lightest colour EZP, as they only have 3 colours to choose from. It's 1-2 shades darker than me and noticably more pink, but I think that actually works well considering cis guys dicks tend to be a bit pinker and darker than the rest of the guy, and my own bio genitals are even darker and pinker than my stp. Design wise, I did get the Natural (uncut) version of it and I think it looks fantastic. It has a great, very detailed texture as mimicking small skin folds, veins, etc. When I look closely on it I see that the head that's "hidden under the foreskin" is actually very slightly more pinkish. The large hole for where the pee comes out is the only thing that looks a little bit off about it when worn. On ftmtransthetics website they do have vid demonstrating it and two review vids as well. Those were helpful for me to watch before buying it. But I've not seen any vids of the uncut version though.
As for "flaws" in my particular item, it has a few almost invisible scratches here and there, a very small bubble on the shaft and in one small area on the underside there's some odd but tiny dark red stains.
As for packing with it... I did notice an issue with it for me that could be of some concern but I've never heard anyone else get the same issue... When I wear it, it kind of "vacuum locks" my own anatomy into the cup part, and after wearing it for more than a couple of hours, I've noticed I get swollen there quite a lot. It was't painful and otherwise doesn't look bad, so I then just remove the packer and give my crotch time to rest and breathe. Then the swelling goes down and it's fine again. I think I accidentally "pump" my T-dick with the packer! So I need to be careful with that happening now and not wear it for longer times, or figure out some better way to position it when using it as a packer.
Other than that, I don't think it looks like a boner just for packing it upwards. The bulge is rather small and soft and looks natural to me. It has a bit of a "flatter" bulge compared to the Mr. Limpy I've used before. I've worn the EZP with tight jeans, looser jeans and looser leather pants so far and it looks fine with either pair. I mainly bought it for the stp function though and not so much for the packing function as I don't often pack anyway.
Oh I got a bonus tip as well: I can use it with briefs that don't have a pocket, by just pulling it out through either leg hole! I don't think that could work with boxers though.
