Death to batteries! - Meprolight M21 Self-Powered Day & Night Reflex Sight w/ Dust Covers

I just got this, and I already like it better than my Eotech. No batteries, built in qd mounts, built like a tank. When there is sunlight, the reticle is bright, very bright. It is dimmer indoors during the day, but still pleasant and clear. The only time it seems to wash out on me is looking across a dark room through a bright window, or into a light source. Something I would have had to either deploy BUIS for or stop and adjust the eotech in the past. (BUIS is faster than adjusting)
Pros: No freakin' batteries, qd mounts
Cons: Reticle is dim in certain specific situations
