This product is NOT compatible with standard NV equipment. When calling for help they do not have answers and promise to get back with you. They DON"T. This product is sent with a strap to put over your head. Very uncomfortable. Even their tech people agrees that it is not wearable for any amount of time. It will not attach to a standard Military helmet. If I have to carry this in my hands it is better to leave at home.

Yes, I know they’re expensive, but the good stuff always is.High quality mil spec night vision with comfortable headgear and none of the “dead spots” mentioned in reviews of lesser products.

Easy to use. Great image!

I don't write reviews. I feel compelled to give an accurate assessment of these goggles to reassure a potential purchaser. Because the price, its a big throw of the dice. Having no experience or insight, this was an impulse for adventure sake. So when they arrived I really couldn't tell if they were knock off junk. Then I couldn't even see anything, so I decided to read reviews and read the one that basically said they were junk and didn't work. I was about to accept this fate, but as a last attempt I turned the batteries around it came to life. After adjusting the front focus and each eye lens focus, playing with the relationship between them I realized that I was able to dial it in. The eye lenses seem to compensate for prescriptions. There is a black dot that disapears as it comes into focus by adjusting the eye lenses. When changing distance of subject continual adjusting is required but easy to get used to. The lighting and clarity is excellent. Getting used to up close hand eye coordination will take practice. I plan use them off roading with IR lights on my rig. I was disappointed that the head harness doesn't have a flip up hinge. Im confident that they are new. I'm glad I took a chance. I will get a lot of use out of them.
