I've had this night vision monocle for a few days now and can safely say that in a SHTF scenario, it's a complete game changer. I'm able to easily navigate by starlight alone. In the woods, I can see camps and vehicles miles away.
If you are a prepper, I highly recommend this over more expensive weapons or other larp equipment. A $1500 gun has marginal improvements over a $500 gun and requires significant training to reap the befits, while this can be used with just a few hours of practice.
