The Maven B.3 10X30 are a good mid range compact binocular. As a full time guide and outfitter I have multiple sets of Binos in differing bands and power levels. When I bought these I was looking for a good compact, light weight, yet quality set of binos to use in the winter when I was lion hunting. Maven didn't disappoint! The clarity and light transmission is very good with these binos and they adjust very well for everyone who uses them from grown adult men and women down to children. No I wouldn't want to take them on a high country mule deer hunting trip where I spent 10hrs a day behind the glass looking for the flick of an ear or the twitch of a nose but for glassing game and we see and while out on day hunts from the truck and getting that closer look at a lion up in a tree or bayed up on a rock ledge they're great! I haven't used the warranty yet so I can't speak on how they are to work with dealing with that, but thats a good thing in itself....nothing has gone wrong with them! I can attest that I have packed them around Alaska on day hikes just out enjoying the outdoors and exercising and have glassed loads of dall sheep, moose and bears in really really WET conditions and they have proven to be waterproof so far! No they are not Swarovski quality but they are not designed to be and the price reflects that. But they are a great mid level choice for a compact binocular!
