The scope works like a champ. I have tested it in several different lighting situations, from pitch black, to moon light, to residual lighting in a dark room. With moonlight and residual lighting, you get a pretty clear image without using the IR light. I was able to make my way around pretty easily. In pitch black, the IR light gives you an incredible amount of illumination. If you are in a small area, it will light it up likes its day time. In an open situation, I was able to get illumination at about 200 feet or so. It was dim, but sill lit up enough that I could make out what I was looking at. Like others have said, you get a little bit of a fish eye affect with this, and the IR light is clearly visible to the naked eye when illuminated.
The biggest problem I had with this set is the Head Gear. I almost returned the whole setup just because of it. I dont have a huge head, but its a good size. My head stretches the chin strap to its limits. I cant adjust it any more, and it is just a little too tight. Having all that pressure on your jaw is quite uncomfortable. Without it, you risk the whole rig flopping off your head. I came up with a quick fix by adding a little velcro to extend the adjuster enough to fit properly.
Once you get everything adjusted correctly, mounting the scope is a piece of cake. Another issue though is the push-button drop-down arm that holds the scope has a little wiggle room, which causes the scope to smash in to your eye if you move your head up or down too hard.
Despite what the description says, you are able to switch the mount to fit the left eye. The drop-down arm unscrews, allowing you to reverse it to fit the left eye. Its a very nice feature.
The features alone on the scope make it worth the price. Most comparable ones I looked at did not come with the IR light.
The best part though is IT IS NOT MADE IN CHINA!
Pros: The scope features are amazing. IR light gets good distance, nice clear image. Will mount on both right or left eye. NOT MADE IN CHINA!
Cons: The head gear is a pain to adjust. Barely fits a medium size head.
