I don't have one and I haven't used one; but I've heard Kyle Lamb talk about it on his podcast and he's a fan. I believe he used one on a moose hunt. He has a channel on YouTube, I'm sure you can find a video about it there.
Kyle and I go back a long way. Kyle had input on the design of the sight. Very fast with the red dot and then just a eye shift for more precision. I can promise one thing, Kyle knows what works. Remember , practical accuracy works.
