This monocular is about as good as Generation 1 night vision can get. Like all Gen 1 NV, it has the fishbowl effect around the edges, but the center was sharper than most comparible units I have used.
The Light sensitivity is great, enabling you to see clearly in all but the darkest conditions. Fire up the IR spotlight and you're in business in zero light. The spotlight can be a little bright in close quarters, though.
I was disappointed that you can see the IR spotlight with the naked eye if you look at the unit. This model is not a stealth unit, but it works extremely well. This is one of few Gen 1 units that you can turn the IR illuminator completely off and run passively. Most other units have a small IR light that can not be turned off.
Overall, an excellent buy.
