I have had one of these on my 223 for 4 years now. Has held zero all the time. Clarity of the glass is more than fine for my 50 yr old eyes in any light condition. Zeroed at 200 yards 4 years ago and still seroed at 200 yards. If you zero your rifle and leave it there,then this scope will be a dream come true. Tracking is iffy at best,but as mentioned, I zero it a 200 and have never had to make any adjustments ever
Pros: Holds zero very well
Cons: non yet
