Work well under the right conditions - X-Vision Night Vision PRO Binocular

These binoculars work well. With the little testing I’ve done on them so far, I estimate their effective range to be about 100-150 yds. I have noticed that they have a hard time with cold weather. In lower temperatures (50-and-below), they drain their battery very quickly, and you’ll have a heck of a time keeping them running. But for $100, to be able to see the other three seasons of the year, I’d say it’s worth it.
