Eo-crap is an OK aiming dot but its not the best when your in the near dark with no light. My sideways battery XPS2-0 provides a more finely resolved dot than my aimpoint T1 micro with 4MOA dot. The aimpoint is smaller and lighter and I never turn it off. The eo-crap is to me faster to use, easier to hit with, sucks in low light without a light, but has not failed me yet. I keep my irons flipped up so they are in the lower 1/3 of the window all the time anyway and irons suck without a light as well...
