Comments about Barska Barska 25 x 100 Cosmos, Water Proof Porro Prism Binocular with 3.0 Degree Angle of View, U.S.A.:
Those huge 100 mm objective lenses are unusually precise for good resolution and color correction. Good collimation and mechanical rigidity. Overall much better than a certain large American astronomical telescope manufacturer's 20 x 80 that I once struggled with. (Also better than some of Barska's other stuff)
