I've had a pair of their binos for several years now. The first year I had them, I chipped the lens on a rock while hunting bighorns here in CO. I sent them in, along with an explanation of what happened. They had them replaced with such a quick turn-around time. I was really impressed. There was also a hand-written note thanking me for being a customer.
I just bought a Savage model 16 270wsm on gunbroker, and will be mounting a Vortex Diamondback on it this summer for sure.
