This is a highly functional and usable night vision optic. If you need to see detail (as on a map or textures or wires) in total or near-total darkness OR if you need to be able to make out facial features at 25 yards (or 100 yards with the 3x eye-piece lens sold separately), and without the overwhelming green-ness of earlier generations of night vision - then this one is for you. If you only need to make out shapes and avoid walking into obstacles in the dark, you can spend thousands less. This is mission-specific gear.
Pros: Usable right out of the box, readily adaptable for helmet or rail, easy to use, right or left side adjustable.
Cons: For many applications user needs to also purchase an accessory package.
