Hey guys. Heads up. a OEM, Uni-trendus.com The reason I am posting this is because the monoculars are REALLY crazy low priced, and almost all are increasing 2-3x after the sale ends in Dec 1st. So I am getting the word out. I have used flirs, fluke, and I have the uti325 uni-t and i use thermals at work everyday. The Uni-t ones are worth the current pricing by far. Take advantage of these prices if you are on the fence. The current pricing was a error, and is lower than their manufacturing cost currently. But they are fixing it after dec 1st. but will honor all sales upto that day. Just a heads up from one hunter to another. Check it out and compare specs. They come with warranties and serviced in Texas
