I've guided many years with other brands of optics, I picked these up in 2020 and was able to compare next to swaros and Leicas on hunts, both over 2x the cost of the mavens and even got the owners of the opposing glass to admit that, if they'd have known about the mavens they wouldn't own their spendier glass. For the money the glass is outstanding. Only point that they fall a little short of the swaros, was the focus knob. The swaros were pretty stiff so they'd stay at same focus going in and out of harness. Not a big deal to me personally and I'm more than happy with my mavens. Every season a client or two makes the switch after I let them compare the mavens to other glass.
