I handled some Maven optics in Redding. Fit/finish, materials, and adjustments were very solid and smooth. The glass seemed on par with vortex Razor glass, which I put VERY high in it's price range, possibly even sharper. I liked the B-series binoculars. A nice piece of technology they offered were screw in cap type lenses that kept dust/debris etc. off your main objective, but could be removed easily. I believe they made em with filters also. I have heard positive things about their customer service as well.
