content: I bought these to carry with us in our travel trailer because they were inexpensive and from a manufacturer with a name I knew. My wife and I love them! They were easy to set up and the instructions clearly tell how to use the diopter to get perfect vision, even though I wear prescription glasses and one eye is slightly weaker than the other. We especially like the quick focus feature where you use a simple toggle lever adjustment in lieue of a dial in the center or the binoculars to focus the scene. They have a nice carrying case to protect them from scratches too.I would definitely recommend them to a friend and we might even get a second pair for the travel trailer.
