Great except for the focus wheel - Vortex Viper HD 10x42mm Roof Prism Binoculars

These binoculars are quality and a great bang for the buck. They're replacing a Razor HD that's MIA, and I don't notice a big difference in optical quality between the two (altho I obviously can't do a side-by-side comparison).

I like that the Viper has complete rubber armor coverage. The Razor has more exposed metal, which is unpleasant to touch in cool weather.

My one beef with the Viper is that my focus wheel is STIFF. I hope it will loosen over time, but it's stiffer than any other new binocular I've tried. It's annoying enough that I'm taking off a star.
