they are great.
If you look at alot of top competitors pistols, you will see cmore on top of their guns.
Hold zero great and are supper tough. I've had one for 9 years or so and changed the battery once.
The only thing about cmores is that the adjacent screws are very sensitive to movement. I would guess almost 10 to 1 over regular scopes. Meaning if you need to adjust to the left 1 inch, a regular scope you move it say 2 to 4 clicks. a cmore you would move 1 click. The adjustments don't have clicks either. But once you get it adjusted they are great.
