I have a 3.5-10x42 that came off of this site as I recall. It is very much like a Leupold VX II in lens clarity and brightness. Seemed to track well when I sighted it in but I didn't test it, just sighted it in. It is on something that gets few rounds through it, maybe sixty in the last couple of years. It is a scope that, to me, has to be priced right and find a niche. I bought this one used because there were a few articles about them that indicated they performed well. Mine is the SII.
