Query: Product defective

I am a long time supporter and user of Nikon products. I have several of their products including rifle scopes, rangefinders, and other binoculars. So, when I needed another pair of binoculars it was a easy choice. The monarchs have clear crisp picture even in low light, and for the cost you can't beat them. My issue with the 12X42 Monarchs that I just purchased is that one of the lense ring nuts was severly bent out of shape. I can't beleive that these binoculars passed inspection, unless the inspector was asleep or blind. I am highly disappointed in Nikon! I hope the warranty process goes smooth.
