I've had a few other brands that have never lost zero or fail to track for a lot less money, a lot less. For example a Swaro PH 1.5x6X42 (same as the S&B) do exactly the same for less, then so have my (no longer manufactured ) Leupold (the horror) 1.75X6X 32 for a LOT less. Granted the S&B's glass is much better, but not at four times the price which is my point. Hell, I have some forty plus year old Weavers that I've never touched the adjustments. My only point is Swaros and many other Euroglass are just not worth the money. Most of their price has to do with labor coasts of course.

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
