## Description

Product Description

Review: The lenses are crystal clear great to use and have. - The binoculars are great they are so clear that I use them just to look at the hedges at my place. The lenses are really good as the image is crystal clear I love. Them. Good price as well. Well made but the attachment to use a mobile phone is cheap and poorly designed the binoculars are wonderful and a joy to use. The straps and bag are cheaply made but hey I have no problem with the binoculars.
Review: Good value ... - Binoculars are good, long range of zoom, value for money ... However if they get wet even slightly the internal lense fogs up and renders them useless ... However once dried they return back to normal
