Xmall STP

My first STP was the pstyle, which worked well for me. Then I got the x small STP from trans guy supply. It works about as well as the pstyle for peeing. and for packing it is great! the name of this product is a misnomer, it didn't feel xtra small or even small to me. It seemed very medium or medium large. It fits in most of my pants just fine. Stays in place in regular men's underware, like tightish boxer briefs or briefs.

I've had a few different STPs in my day, and this one is not only the one I've had the most constant success using, but it's also been *the* best when also used as a packer.
It's small enough to be a functional and realistic pack, and the open design is great for effortless flow control. The general appearance is also good and realistic.

The only minor drawback is that the small reservoir/scrotum can sit a little lower, and has to be tilted forward quite a bit after use or else one runs the risk of about a teaspoon of pee remaining in it. Depending on one's body, technique, etc. this might be negligible, and I'll admit I'm still experimenting with different holds, etc.

Very satisfied, especially after having less successful STP and packing experiences with devices costing a lot more.

It's flexible enough that it doesn't look like a perpetual boner, and comfy even when not planning to use STP function. Good buy for the price!

Hard for me to use, but the length and detail are ideal. It's hard to find an uncut stp so 👍 but unfortunately not for me

It's squishy enough that it packs well (up & down), and light enough that you don't need a strap if your underpants are snug. It's pretty easy to use and I haven't had back-flow. It should pass at a glance. The urethra is like a boba straw but if anyone can see up your dick at the urinal... you need to work on your technique lol.
And above all else, it's uncut, reasonably sized, and under $50. Can't think of a single other STP that ticks all those boxes.
