Nikon brags about their "no fault" warranty. I guess that includes sliding down a mountain!

I love my Nikon Monarch 10x42mm binos. I don't have a lot to compare them to (I've only owned a pair of cheap $50 before this), but I have spent hours upon hours looking through them and have nothing but good things to say about them. They are very clear through the entire field of view. They also have great eye relieft as I wear glasses and have a hard time using some binoculars.

Thats my 2 cents.
