I don’t own one, but I have handled it. I think it’s a great scope, but for my purposes, I prefer the 6x and 10x. I have four each of the 6x and 10x, along with one of the 3-9x.
I also just picked up an SWFA 5-20x a couple of days ago.
If the S2H scope wasn’t coming out this fall, I probably would have bought a 3-15x to try out.
