Well, so far so good. I have verified its accuracy with known distances, or verified my known distances with the range finder, ha. It doesnt work well through a windshield, esp if dirty or wet. (duh) It has very clear glass, I find myself using it as a spotter rather than my binocs since it is so small and light weight. I have ranged deer up to 300 yrds so far, and my longest range period was a feeder 700 yds away. But damn it is hard to hold still, prob need a stick or something. it is threaded on the bottom for a mount. Anyway, 5 stars so far.
