I have the 3-18x44. I only have about 40 rounds with it. My opinion thus far:
The optical quality is good - A bit better than my mid 90s Mark4s.
Adjustments are not a crips as would prefer, but usable.
Lots of adjustment - dont know the exact amount, but lots than you need to get to 1000 yards with 6.5 CM.
The reticle is excellent.
The illumination is ridiculously bright. Not useful for low light applications. My only real complaint.
