I haven't tested mine out in the field yet but they are very highly spoken of over on Snipershide. Guys are reporting consistent ranging out to 1700 yards and usually 1800-2000 on cattle, elk...
I can coment on the feel of it though. It is Tiny, I had a Bushnell Yardage pro 800 before this and that was small but I can almost wrap my hand around this whole thing. It is 8x so I will probably not pack my binocs anymore, just the RF and spotting scope. Glass is what you would expect from Swarovski, crystal clear, crisp image.
The true test will come in the fall but I am optimistic.
