For what it is - SIG SAUER ROMEO5 Gen 2 1x20mm Reflex Red Dot Sight

What it is, is green, so much better than old red. My battery arrived dead, so was not off to great start. As noted by others it is a not a 1 MOA dot as listed under features. It listed under specs as a - Dual reticule:2 MOA Dot or Circle Dot. It is NOT and was disappointed to find this out. Investigating after (I should have check first) on Sig website, I find part of the problem is Sig's fault along with Optics Planet. Sig has an "Elite version" that is only in a red reticule that actually has a Quad Ballistic Circle Dot 2.0. There is no elite version for green. Newer style turrets without cap to lose are nice. On fence on new I-beam mount. Old style mount could use Back Up Iron Sights without having to remove. New I-beam ones do give a bit better field of view.
