Pretty much what the title says. Which STP do you use? How well does it work for you? Have you used it at a urinal? Right now I'm using the number one laboratory Model A. I'm still learning. I'd say it works about 75% of the time right now. Haven't used it in public yet. My goal is to be able to use the urinal with it. I've used the urinal twice but both times were with a medicine spoon.

My med spoon works well, why buy something expensive.

I've had most successful use with any funnel-type STPs. I don't know how I could get medicine spoon to work (haven't tried but skeptical) and the nipple is only half-efficient for me.

I've found that funnels work, but are messy.

Yeah, that is also true. I don't like the moisture that is left behind.

I use the Mr Feenis. It works great and I haven't had any spillage in a long time.

I use the Number One Labs STP, original.  It works well for me.  The tube and opening are large enough that I don't really need to restrain the flow, provided I am positioned and angled properly.  And it is firm enough that I can press the back part up against me to create a confident seal.  I have not yet used it at a urinal, but I think I will be able to do so.

I used a medicine spoon type STP and failed...multiple times. Almost all while in the shower.

I've tried the mr fenis and could not get it to work for me.
