Good optics, mechanically reliable and robust. Very good value for money.
I have several old steel bodied made-in-the-U.S.A. Weavers: K4s (4x32mm, if I recall correctly, K2.5s (2.5x20mm), Micro-Trac variables (1.5-4x20mm,) and one of the current production (made in Japan, fully-multicoated optics, aluminum alloy) Classic V9 (3-9x38mm) models. I bought all of them used for very reasonable prices and they all work as they should.
