The only issue with the reticle on my Trijicon reflex occurs when looking out of a dark area into bright sunlight. (Imagine looking from inside a shack out into bright daylight.)
The fibre optics cannot collect enough light to illuminate the reticle bright enough to counteract the bright sunlight outside. I have the smaller/older version of the Trijicon
That is a pretty specific concern, I agree.
And that being said, I still prefer the Trijicon to an Eotech.
