it's very bright even in sunny day. It's fast coz of the shape or reticle. It's auto on/off. Not afraid of rain. It's sharp&crisp with my astigmatism. Yes, it eats off some of the pov couse of being bigger but it's ok for me due to I use both of my eyes for targeting. No parallax coz of being prism. Win win i suppose. M.b. it's worth consider a new x1 Prism from Swampfox that is somewhat the same.
