Only my opinion:

Scare me! Used one in 2001. I had the holo and the red dot sights...I think it was BSA?...

Waaaaay too much movement and jumping around with that sight for me...I like to see my pin lock on my target...that red dot was bouncy for me....I don't think I had the hand shakes that bad!

I use a single pin adjustable by toxonics....soon to buy an HHA site...
