They advertise on one of the outdoor channels. Other than that, I have never seen or heard of them. I'm usually cautious of any optic product that claims to provide a lot of quality for the money. That's not normally the case. Whenever a scope's price and quality seem to good to be true, it usually is.
Just curious, what is the price of the Nikko Sterling? I may need to eat my words. Maybe they are a great value.
