I bought a pair for LE elk hunt last year, and wanted to love them but ended up using my swaro's almost the entire trip instead. I got very quick eye fatigue. If I looked for more than a minute or two and took my eyes out of the binos, the regular view was blurry for a second, like I could never get them perfect for my eyes. Everyone in camp shared that aspect. Atmospheric conditions like looking into any smoke, fog, snow, rain, etc... for some reason the view was much worse than looking through other binos at the same time as well. I kept them in the truck and used them to glass while the truck was idling but I still preferred packing a tripod and using my 12xNL for everything else. They are going in the right direction, but for me they are not good enough optically for me to use them yet. The new model is much better than the original model however. Mine were the 16x. If I had unlimited funds I'd keep a pair of 12x Zulu in the truck. For anything else, I'd still pack in 12xNL and a small tripod for the FOV advantage.
I'd run a pair of 12x for 3d archery or TAC events though. Would be great for that quick look.
