I've had one for a month or so. Bought it mostly out of curiosity and to compare it to my Terrapin, i'm not sure yet if I'm going to keep it.
In the past i've owned a Leica 1200, Leica 1600 and also had some time behind a Bushnell Arc 1500.. the Kilo beats them hands down.
Extremely compact, stupidly fast ranging, angle compensation, good warranty. I've ranged reflective targets out to 2700 yds. I haven't been able to test it out on animals at long distances yet.
Negatives are no tripod mount and the beam is a little large.
I highly recommend this unit for the price, however If you're an extended long range shooter, there's something else just around the corner that you should probably wait for.
