Title: Worked well - no problem with eye fatigue watching football
Review: Based on another reviewer's recommendation, I at first got the Bushnell Powerview 4x30 instead of these Xtra-Wide 4x21s. But I just wasn't satisfied with the field-of-view of the 4x30s (not only do the specs overestimate their ability, but they only apply to the width of view, not the height). With the 4x21s, the field of view actually seemed to be larger than the specs indicate, and provided a nice round image, as tall as it was wide. It was like the difference between night and day! Also, I didn't experience any eye fatigue as the other reviewer mentioned: this may be because I was watching football instead of basketball (less constant action and movement). But to be honest, if I get eye fatigue from these 4x21s, I would still rather use them than the 4x30s--I can take a break or let a friend use them if my eyes start getting tired (besides, I never like holding binoculars up to my head the whole game anyway).
Is the review positive or negative?
