Hey gang,
I hate to say it, but more often than not, these reviews are going to be biased in some way, and this is not typically due to any "sell out" as implied above. First off, we are all human and as such, when we have positive experiences with one brand this is likely to come across in our protrayal naturally. Sometimes a lot of emphasis is put on personal ergonomics as well, which obviously won't work equally for all as every individual eye, face, hand is a bit different. Even when folks try to be totally neutral and just use manufacturers listed specifications for comparisons, we find these aren't TRUE comparisons at all.
Why?!?... because there are no set criterion for testing and listing optical specifications. Eye-relief is probably the most commonly MISrepresented specification out there actually. I've found, variation in this single "measurement" can be SO different that some manufacturer's listed specifications may not be repeatable to even within 4 mm when tested using another company's measuring technique!!! I've had multiple cases where someone has told me, "I tried brand X with an eye-relief of 17 mm and it wasn't enough so I didn't bother with yours..." Invariably these folks are amazed when I encourage them to try anyway and the glass in their hand (with a listed 16 mm eye relief or similar) works perfectly well behind their glasses.
I could cite another instance where one competitor's specifications improved overnight with the printing of a new catalog when no change was made in the glass... "Don't know what happened went to bed one night and the following day the product was even better than we remembered!" ;p Or how about "Waterproof" are any non-waterproof binocs made anymore?... This is another completely meaningless term since there is no set performance standard you need to meet in order to use this term. It's become as empty as "NEW" or "Improved" on your laundry detergent bottle.
My point is to take all of these reviews with a grain of salt. They are based largely on opinion or dependence on how scrupulous or reputable the reporting company cares to be in their listings. Many are very conservative in their claims and some will always boast nearly unbelievable claims. In the end though, you CAN NOT use listed specifications alone to make any judgements between differing manufacturer's products unfortunately. You need to either run each test for yourself using an measurement technique, or depend on the old tried and tested.... trusting your eyes!
Here again, I will add one additional caveat, and that is that a quick comparison at a well lit showroom may not be enough to tell how the product performs in a variety of lighting and environmental conditions. I one time bought a car in a shaded showroom that looked maroon, but when the sun actually shown on it reflective flakes in the paint made the car almost glow PINK!... As a result, it is often best to take adbvantage of some reputable dealer's that have try befor you buy or even no hassle return policies. In this way, you can insure that you have made the right decision under all conditions. A slight difference in view (or barely perciptible) lasting a minute or so in a well-lit showroom may amount to a world of difference over an entire day in varying environmental conditions. Cumulative eyestrain will make itself known over time!
