I've had one for a few months now, it's a good unit for under 100 yards in forested areas and out to just about 200 yards in open country. I ended up buying an LS420G laser/ white light/ IR illuminator to improve performance in absolute dark conditions.
I also have an Sig Echo 3 IR optic and they each have their strong and weak points. I like the Holosun for a clearer picture of the target but I can find live targets easier with the Echo 3.
