I am a military combat veteran, so I have a lot of experiance with night vision. This is a Gen 1 analog low light device with a classic green display as you would see in the military. For a Gen 1 this is an outstanding buy. Most Gen 1 night visions will have a small spot or 2 in them which is natural, and so did mine. Mine was located in the outter right portion of the monical and is hardly even noticable. The clarity is way beyond what I could have expected out of older technology like this. With two focal lenses, one in the front and rear, you can dial in for a very crisp picture. The field of view is a little narrow, but it made clear that it would be being a monocular. I am in a suburban area with a lot of ambient light bouncing off of the atmosphere and I can still see tons of stars with this product. I also like the fact that it takes AAx2 batteries so hunting for power is not a problem. Additionally, it has an infrared light that you can turn on and off if you wish. The housing is also fairly good and feels natural in my hand. If you are wondering which night vision to purchase, stop looking and start buying this before it sells out.
