The first pair of these I got had some kind of focusing issue, perhaps it was poor collimation. I re-ordered (even though the price had gone up $5) and this binocular is very, very good. I appreciate the eyepiece setup where the diopter setting dial is up by the main focusing ring freeing the eyepiece dials to accommodate relief for eyeglass wearers. Works perfectly for those without glasses too. Very bright view, these are great for bird watching or any outdoor application. I intend to use them when working as a volunteer at golf tournaments (or as a fan) as I often need to see what's happening 300 yards away. I'm glad I re-ordered them and I would definitely recommend them to friends.
