These are a pair of high quality and well designed night vision goggles. I purchased the NVG7 with an optional 8x magnification lens, and my primary use of this device will be as a high power binoculars. I already tested it a couple of times outside, and the results are impressive. I'm able to clearly see objects at 150-200 yards whereas when I tried to see something without the night vision in that area it was totally dark. The body of the NVG7 looks durable, but it is really light at the same time. I'm very satisfied with my purchase and recommend it to anyone who is looking for good night vision.
