White letters on a black plate and smaller blue one. Left eye only, both barrels clear with a diopter setting of 0. Numbers are focused in the right barrel, but smaller than in the left. Image gets incrementally larger with each click, and looks the same size as the left barrel with the diopter at +2.~70ft. Power meter on the next door neighbors' house with black lettering on a white background, and an LCD readout. Left eye only. Left barrel focused. Right barrel fuzzy at 0, pops into focus when the diopter hits +2.At both distances, the diopter must be set to +2 for a clear image when using both eyes.edit: I've been redoing my comparisons of yesterday, since most of my viewing was with the diopter set at 0. They are sharper now that the diopter is +2, not quite as clean edged as the EDs, which sharply delineate separate items, but it's very close, and the 10x shows more detail. Seem brighter, too. Same neutral color rendition. Wonderful. So the diopter setting is off, but the bins are working fine.editing over my edit: I called EO and talked to my original salesperson, and believe the diopter being at a different setting is a non-issue, and I will keep these.</blockquote>
