Review on Nikon 7239 Action 7x50 EX Extreme All-Terrain Binoculars in Black by Clay Elmer

As I looked through these binoculars with one eye, every side was perfectly clear. However, when viewed with both eyes, the center was sharp and the edges blurry. It was an unbearable visual effect. I had to send them back. Nikon should get 1 star for this, UPS should get 1 star for slow shipping back to seller, and Revain should get 5 stars for allowing the binoculars to be returned and issuing a refund within a short time. Nikon should also be ashamed and embarrassed that they ship their product without adjusting it to fix this collimation error. A very bad moral and unprofessional company by Nikon as they have distressed both the Revain supplier and the end user due to their poor decision making and apparent greed.
