Pros: Quality of optics, durable frame and excellent lens coatings make these a joy to use.
Cons: Lens coating is optimized for hunting, not general purpose use.
Steiner has built a solid reputation over a number of years for offering an extensive catalogue of hard use quality consumer and military/police optics. Over the past thirty years, I have owned a number of their binos and have used them on active duty in combat zones as well as for hiking and star gazing. The 10x26 Steiner Predator binos which are the subject of this review were purchased by me for use in Iraq as a lightweight, compact alternative to the full size USMC issue binos. They proved more than adequate in that role. While they have a relatively narrow field of view, they have clear, distortion free optics and excellent light gathering capacity considering the size of the lens. Their light weight and small size make them very usable where weight is a concern. The rubber armor and magnesium frame make them able to withstand abuse. The focusing mechanism worked smoothly and without any play. Once focused, I rarely had to make adjustments. I have used them side by side with similarly priced compact binos offered by competitors and they are sharper, with better light gathering capacity and ergonomics. You can spend a lot more without getting an appreciable increase in performance. These binos will not replace full sized binos but they are a good supplement.
