Very good! - Primary Arms The SLx 1x23mm Mini Red Dot Reflex Sight

Overall I am totally satisfied.

Construction
- I have not had it long, but optic feels durable
- battery tray, while not tool less, is simple and works well.
- brightness adjustment is easy to use.

Dot
- I have some degree of astigmatism, but the 3moa mitigates much of the starring I have experienced with 2moa dots. (6moa is the best for astigmatism, but I prefer a 3moa for competition)
- I have experienced no zero shift so far.
- there is a small amount of "flicker" or "tracing" with fast movement, but imo not an issue.

Looks cool too :)

For context - I also ordered a Romeo 2 pro 6moa (on sale blem), which was a little more cumbersome to use (battery tray was tricky, brightness adjustment pretty cumbersome) and while its a really nice dot and versatile optic with included shrouds, its a little large for my taste and the cumbersome controls kind of deterred me... not to mention the price point.

Overall I would recommend this optic!
