I bought these binoculars and they received very little use. The ring that you use to focus them broke. I sent them in for Warranty repair (had to pay shipping) included my warranty card and proof of purchase but was told that the only way that part could break is if they were dropped very hard. This never happened, they were treated gently and only lightly used, never dropped. There is not a scratch on them that would have happened if they were dropped. This is a moving plastic part that was obviously defective.Nikon is refusing to honor the warranty
