I have this one.
I haven’t missed a deer since I bought it.
I like it specifically because the dot gets very dull, and is a 2moa size, which appears to be the smallest I’ve found.
It held zero for an entire season. then sat five months, needed to be clicked a few clicks on windage. Has held zero since.
I shoot the bow a couple times before I head to the woods.
If you don’t like it it’s free returns on Amazon.
I also had the fastfire2. It was too bright for me. But I did like the tiny size and open field of view.
I’m fairly certain
