I honestly don't give a rats *** about the battery life of Eotechs
I'm loaded with CR123A's due to the battery commonality between my Surefire's and my Eotechs and if I needed some I could go out to an electronics store and pick some up (who needs camera batteries when SHTF
, they'll probably be the only things left)
I also find the reticle faster and more useful than the single dot found on the Aimpoints.
But if you have uncorrected astigmatism forget about the Eotech.
