its Big, WOW very happy with this purchase. super soft, Ilike the capacity and length, this is easier to hold and pee rapidly with if you are familiar with using an STP. I especially like the balls because the firmness helps keep it in place to STP. They are realistic looking in my underwear, and this packs surpisingly smoothly for its sexy size. I haven't ordered a rod, but love this to STP and really love how well it packs! it can pack down where you get the biggest bulge, or sideways semi erect, will lay it over more flat at the shaft. Or you can readily pack up with it too, it WILL SHOW like its hard if you want it to. I am a tall guy so like this size as it fits me proportionately. Superior as a packer! learning curve if you are not experienced at STP. For me it peed perfect first time, already packing it this evening. Super quality at an amazing price! hope they restock C4 soon, please keep this STP available in this size, it is much easier to use, and the shaft length, diameter, ball size and ball shape really helps! I hold the balls with my legs to pee, just one hand is necessary on the shaft. Pull the whole thing up higher to pack, lower it just while peeing. It fits in my pocket jock strap and in a packing harness. I needed more size and this is perfect! the hole placement on the cup is very good, different shapes can fit different body types, wonderful quality here! thanks Axolom!
