Pro's = night vision, multiple profiles for diff guns/ ammo, ballistic calc, recoil activated video, video recording (goto hunting and see vids I took with it daytime), 18 hour battery life, ffp mil dot reticle, very accurate, and a whole lot of other cool features.
Cons = heavy pig. Grainy at high magnification.
I personally love mine, especially for winter plinking/hunting when the days are so short. I definitely prefer a real optic in daytime, though. With the ATN quick release mount it is easily and quickly transferable to another rifle, holds zero incredibly well. I'm constantly juggling it between 4 rifles.
