I really really like this thing - Swampfox Liberty II 1x24mm Reflex Sight

Best red dot for me by far. Even with a bad astigmatism, the dot is pretty clear! Although I leave it on the cross hair only reticle because that works plenty good for the handgun distances I train at and my astigmatism basically doesn't exist with those non dot reticles, just obviously not as precise of an aiming point. Only real negative so far is I do get some emitter glare, but I can live with it. Overall well worth the money, especially after trying much more pricey optics.
