The basis I think is to make comparisons between the bin under review and other bins others not. Compare and contrast different features especially ones where it succeeds well and others were is is just mediocre or fails compared to other bins. Compare it with other bins both below, equal and above the same price point. What compromises have been made? How the do the ergonomics work for you (and perhaps for others ... if you have big hands or small IPD how might it work with other folks?).The usual things people want to know is: centerfield sharpness and edge of field sharpness and how they cary between the extremes; brightness and contrast; CA (longitudinal - center field and lateral - at edge of field); ER (does it work for you? can you see the whole field? blackouts? what about with and without glasses? Sunglass work if you don't wear glasses); stray light (how well do it deal with off axis stray light say to with 20 or 30 degrees of the sun?); FOV; focuser speed (how many turns of the knob from 10 feet to infinity).You'll try them close to home first but take them out birding to get a feel for how they work "for real" (does the dipter setting stay set or does it get knocked about?). Birds (common ones like chikadees or even crows) make great subtle targets for evaluating bins for color rendition, contrast, CA and the like.It's also good to notice your immediate feeling when opening the box and the how those views changed over a day or twos use and then even return and see how you feel after a week or a month or even a year. We all know the "Oh boy this is the best ever" feeling one can get with a new bin.Read a few other bins reviews from here. There are plenty of good ones: Sancho, Steve C, FrankD, Surveyor, Ceasar, Ronh, Henry Link (a bit more technical), etc. (Apologies to anyone I've missed). Find reviews from any of the regulars and see how they do it .That's about 435ish feet at 1000 yards. On the wide side for an 8x</blockquote>
