Several years ago, I received a pair of Brunton Eterna 10x42 binoculars. They were excellent binos, in my opinion. Although they did lead a fairly easy life, I could no longer get a simultaneous focus on both sides. Brunton warrants their binocs to be free of defects in workmanship and materials for life. Brunton no longer makes that model. I sent them back to Brunton and two weeks later a pair of 11x45 Eternas show up....no hasssle....no quibble....no charge. THAT IS THE WAY IT OUGHT TO BE! I place a lot of stock in a company that builds a good product and stands behind their product. Brunton nailed it and I thought all my fellow hunters would like to know.
