Stieners are just about the most overrated glass going. There are a lot of binos around that have better optics and are more rugged. Mine fell from the floor of an f-250 to the ground, while in a hard padded case, and they wanted $250 to re-align the left prism. To me ruggedness is also pretty important.
No shit, my compact stieners fell off a lawn chair in my garage and the prism dislodged and they wanted 80$ to fix a pair of Binos I paid 135$ for. They sent me back a "factory rebuilt" pair that had double vision, i shit you not....
So i griped about the shipping charges and inconvenience and they sent me the next better pair in their list product list, and they were brand new. I took them out for a summer hike in the rain and BOTH tubes fogged up....
Then they sent me another brand new pair and I have had them for 2 years but they only go turkey hunting or bike riding. I am paranoid to do anything else with them!
