They failed forms test miserably, I am hard on stuff generally and don't care much about my "tools"
I have 2 due to an insane discount I receive. 1 I mounted on a rifle I screwed together almost 6 years ago. and it has been perfect.... It's been west 7 times and east 2x, I've shot deer out to 500 and targets to 700. It has never been adjusted one time in those 6 years on a custom 6.5. I was just accidentally standing on it in CO last month and made a first round hit at 635 after.
They've been good and Ill buy more. I have multiple trijicons and night forces as well so don't arrest me rokslide..
I am not saying they are the best, thats just my .02
