I have been absolutely amazed with the scope especially the glass. The tracking is amazing as well. This is one of those rare instances where I truly believe you get more than what you pay for. I think that the SIII Series is The best kept secret in the optics world.
I've had 2 of these scopes for about 3 years on a 243win and a 7mm rem mag. After over 900 rounds and several elk hunts with the 7mm it still tracks perfectly from 100 to 1400 yards. Unbeatable scope in this price range.
Scope is fantastic. Sharp, contrasty, tracks excellent. Perfect in every way. Could not be happier. Thanks for building such a great product.
