Coincidentally, I just ordered Vector Micro Prism Scope (x3) - I will report on that when I get it. I played with Vortex one today at a comp and I liked it. I also like Vector in general, everything of theirs I have used or seen I have been impressed with, like proper impressed above Vortex and I own a bit of Vortex gear. But at almost half the price and 3min from my place, I thought - nah, I will click&collect and see how we go. Absolute wort case scenario I have enough funs to give it a home 
TBest case, I will order another one.
On that note, I am not sure how much of it is true, but something I found on a forum while researching tonight:
“Vector is the front end brand of the company that makes a lot of the Chinese optics. PA, Vortex, Sig, they’re all coming from these guys.”
So there’s that, is it true? NFI, but certainly within realms of possibility.
