Yessir. Not as much time as I have behind the SLC's and EL's in the past, but enough in some low light situations to develop an opinion. At our Sportsman's location, everyone referred to me as the "optics guy," because I was always taking glass outside to compare when things were slow. I spent a ton of time glassing that big face behind most of the binos that Sportsman's sold for a few years. I watched lots of sunsets and lots of bedded animals at all hours of the day behind a multitude of optics from a tripod.
I'm NOT a fan of the NL's. I hate their ergonomics, the eyecups feel like they're trying to dig my eyes out of my head with an ice cream scoop haha. And in hand I just hate how they sit in my palms and fingers. They feel more... fragile? when compared to EL's or even SLC's.
Optically though, the NL's are great, though they're not the "game changer" that Swaro's marketing department would have you believe. I personally feel like the success of the NL Pure is 95% market hype, and I feel if guys could somehow be placed behind an NL Pure, EL, SLC, Razor UHD, Leica Noctivid, etc. blindly, the "differences" would be more difficult to distinguish, and the "best" binocular argument would lose water. If you can swing $3500 for binos without breaking a sweat or batting an eye, have at it. But I don't feel they warrant the fanfare. Again, they're optically great, but I'm not even a little bit tempted to save up for a pair of them.
