This could be the best option for me both as a packer and STP. STP works flawlessly since I have started using it, I've never spilled with it (I've had a previous STP so maybe that gave me an advantage) but over all i think the cup is positioned perfectly for my anatomy and the shaft is perfectly long enough. I peed with it both outside and at urinals and everything works and LOOKS great. Now why I'm saying ,,could be" is because I think It's a little too big for packing (I'm a smaller guy) and the balls are way harder than they have to be imo. Also the shaft is also kinda stiff and could be softer so it would ,,stay down" more naturally. Without underwear it looks like a semi-boner. But when i compare the packing to the EZP I used before, it's finally normally positioned penis and not some weird piece of silicone i wear upside down. I'm fully comfortable with it while wearing tight underwear. I kinda wish i could use boxer briefs but then it looks totally like a boner. I pack using a custom jockstrap (O-ring + elastic harness just over my hips) and that's for me the best and comfiest option + it's super easy, discreet and fast to take out and piss. The looks and coloring are totally sufficient for me, I picked out the perfect skin tone so it looks absolutely natural. Now I'm just regretting I didn't get the movable skin, that would be an awesome final touch that would make up for it being kinda too big hehe. But these are just my personal little issues but overall it's amazing and I'm very happy with it.
