The turrets for me were the thing that took most getting used to on this scope. Those and the floating centre dot reticle I guess.
I am used to taller, 10 MIL/Rev turrets with larger spacing between clicks and large numbers, so to go to the lower profile turrets with closer clicks took some adjustment. At first, I was much like
@C_R_Slacker and had issues trying to determine if I was a click out and spent quite some time adjusting the cap on my zero to ensure that I was happy.
Once I played with it a little more, ran it in a handful of training sessions and matches and just got used to it, the turrets have become second nature and dialing to where I need to be seems to be faster. I am now a huge fan of the turrets and going back to a NF or a Bushnell feels slower to me, even though I can easily see the MIL markers.
As for the 2nd turn window, I have yet to shoot that far in actual use (topped out at 13.3 MIL with my 6 Dasher) but playing with it (on my scope) didn't appear to be an issue. Yes, there is a noticeable "oomf" required to get over that second rev, but it doesn't bother me and it's not as bad as some of the reviews I have seen out there.
The illumination I have actually used for some trickier shots into dark scenery and low light and can say that it works very well without blurring the reticle for my eye. Best illumination I have used to date. The only issue I have had so far is the one time I accidentally bumped the illumination on between stages, started the next stage and had it at max power (which I quickly shut down).
