These goggles are lightweight, have great resolution, are extremely sensitive in low light, and are very easy and comfortable to use. Properly adjusted I never get eye fatigue even looking though them for over an hour. During a cloudy night with nearly a full moon I tested the visual acuity with an eye chart to better than 20/50 vision (normal vision is 20/20) which is very good based on military testing reports. I could easily walk through the woods without using the built-in IR illuminator and could see individual leaves on a heavily wooded country lane out to about 50 yards with even a slight misting of rain. Overall the image appears clear, bright and sharp with a very small amount of "sparkle" or noise on dark cloudy nights. In addition, the optics are good and show no discernible distortion. The 40 degree field of view is bit of "tunnel vision" but after awhile you get used to it and learn to "scan around". Overall a really great NVG!
Pros: Light weight, good resolution, low noise, extremely sensitive to low light, comfortable and easy to use.
Cons: A little hysteresis in the optics adjustments but perfectly useable
