I bought a pair of Geovids used off Craigslist last year. They worked fine under 200 yards or so, which is as far as you could get when I checked them out. On my way home I stopped and was trying them out but they wouldn't get past 600 yards and 600 was hard to get a read. I contacted them and told them my situation. Guy said to send them on in. They told me it'd take a month. Two weeks later a brand new pair showed up. No complaints here.
