They are assembled in the US but I believe the B series is Japanese made glass. Not a bad thing, IMO. They seem to be gaining a lot of steam and they make some lofty customer service claims. If I ever replace my Nikon 8x30 set I will probably try the B series MavensThey're not a random Asian company. Yes, the C1's are made in the Philippines, but the B series is the ONLY made in the USA binocular in the world. Even "Made in the USA Leupold" builds anything that's not a scope in China. The guys that run Maven are in Lander, Wyoming, and all their B series are fully assembled and tested there, and all other optics are also tested there before shipping. When I first started looking at them, I called to ask some questions and ended up leaving a voicemail. At 7:30 PM Mountain Time, my phone rang and it was one of the owners, returning my phone call. I could tell he was busy as we were talking, and he said he was assembling Binoculars to fulfill some pre-hunting season orders. They are a small, mom and pop type operation that is scaring the big boys TO DEATH, and I see them hanging around for a long time. The guide industry has largely started to convert to the Mavens even, so they've got a good enough following there realistically to help keep them in business without all of us converting over as well. I would never worry at all about them going anywhere. I would worry about Vortex disappearing before Maven personally, at least Maven sells a decent product.
