You should quantify your experience using an EOTech. I've used them for 12K rounds and Aimpoints for just over 15K. The EOTechs I've owned, 512, 551, 552 would change POI if they got hot. Batteries never lasted more than a few hundred hours. The 551 was the worst, it got to the point that after about 40hrs it would start to give the bright/dim indicator that the batteries were going when turned on. The would also not hold a good zero if removed, LaRue mounts fix this problem but the Aimpoint (any of them) is a better optic by light years.
