I'm reading up on them as we speak. I really like what I'm reading so far.I have no direct experience having only recently acquired mine but having done some homework, reports since introduction are quite positive about performance and reliability. The company is owned/managed by ex-Nightforce and Kahles professionals
that placed very high emphasis on reliability, and back the product up with a lifetime/transferable warranty. I would add that there are some unique design features that claim "superior" long term durability, particularly focused on the turret system.
