I had a big Celestron 16x70 IF porro for review. One barrel was a little "off" and it was a bit picky to get both focused the same on the same spot. What I concluded was that the 16x with the binocular was at least as useful as 25x on a good 80 mm spotter. Others may be different, but I don't care for the strain on one eyed glassing. DOF pretty well sucks on higher magnifications, so the binocular vision is worth its weight in gold as far as I'm concerned.
Sent the bad unit back to Celestron and never heard back. It is freaking HUGE, but has good potential.
Another thing I am inclined to believe is big eye satisfaction is more related to how well the unit focuses for you rather than who made the unit. Proper focus in a shallow field is pretty valuable.
