The pic and name makes me think it's a slightly better olight. Maybe it's the programmer in me. Replace "o" with "p", but barely so, so it's just "pa".
I like that like the olight S15 is has a lanyard hole that allows it to sit flat. The lack of a tail clickie isn't a big deal to me so long as it has tailcap lockout, and it'd be better if it had electronic lockout too. Of course I don't care about any of that if it doesn't have a good low mode and UI.
That $25 price is very attractive. I'll consider getting one to carry instead of my RRT01 when I can expect it to get sandy...control rings and sand don't get along well.
