In short, I liked it. As far as in my opinion it is good equipment with excellent value features that an optic can have right out of the box. The attractive thing for me was that it is offered with a 1.4-inch riser that can also be used on the top of AR rifle.

The Sig Romeo 5 battery life timing is 40,000 plus hours that actually made merely on it for a longer number of hours without any worries. The MOTAC motion sensor technology of the sight is really sensitive and works very well in every manner.

However, I would like to mention it here that the red dot itself is enough bright even when there is bright sunlight. It is easy to be shot back at a distance of 100 plus yards with the Sig Sauer Romeo 5.

The only thing that I wanted to test but I could not is how it performs at zero. I happened to use it once when the wind picked up to 30 miles per hour and I failed to confirm zero with certainty. Though it did fine still I want to know about the zero.
