I’ve run a few and have found the coating to work as advertised. It will NOT help on a inadvertent “hog breath” from fogging up your lense.
This is my experience as well. I have a 2-7 3500 I bought with the 50 dollar rebate. It was great in the rain on the Saturday of our opener this year. It did, however, for up a few days later when it wasn't raining, but was 18 degrees out and I was breathing heavy with a mask on blowing air up onto the lens. Just like every scope I've ever used does.
Hot breath on cold glass will fog up for a minute or so, but it's not like internal fogging, it goes away asap.
