I chose this binocular for my wife, who usually has a difficult time with setting binoculars just right for her eyes. The 7x50 design gives a huge 7mm exit pupil, which allows for a larger margin of error while bringing the binocular to your eyes. For that purpose, it has been great for my wife. She is consistently able to get a clear, unobstructed (crescents, tunnels, etc) view.
The focus wheel is smooth and easy to operate. The diopter adjustment is very easy to operate--almost to its detriment. It is far to easy, in my opinion, to change the diopter setting with general handling.
