Bought this unit in hopes it would be on par with the other knock off optics i have for airsoft, in the sense it would kind of work under NV. unfortunately the optic in NV mode is so bloomed out and distorted, its actually better under NV on the regular setting at the lowest, it is still way to bright though. edge distortion is very bad on day mode. my cheaper knock offs are better then this unit, maybe I got a dud? maybe that's just the way these are.
