Yeah it's not terrible but for the money, I was disappointed. The build is pretty shoddy (made of polymer, not real glass, fragile housing, etc), had trouble adjusting the elevation and windage (must be loosened screws first but if you loosen it too much, the battery falls loose and breaks contact), and it also cut out a few times from the recoil during shooting. I didn't trust it so I returned it. Sig CS was great and offered to send me a brand new one in a different dot size but I had already returned it at that point.
