Shipping was fast and everything arrived neatly in a box in which we received the Binocular Tripod Mount Shoulder Strap Carrying Case User Manual K&F Concept is a fairly well-known brand in the video industry for lens adapters with good build quality and these binoculars meet the brand name requirements. These are binoculars with a magnification of 12x42 millimeters, they have a classic design with clean lines, the footprint is minimal and the outer surface is knurled for a good grip. The construction is good, it has an ABS housing and two rubber covers to protect the lenses. It is IP68 waterproof to a depth of 10 m, which means it can survive the rain in the forest while walking. Focusing is done with the central button of the binoculars, which is easy to use. On the other side of the focus knob is a knurled screw that can be removed to attach the tripod mount, leaving your hands free while observing with the binoculars. The vision is clean and clear, without distortions or double contours. They are excellent binoculars for observing nature, e.g. for bird watching and observing wild animals at a safe distance without disturbing. It offers excellent value for money. I hope I helped you choose the product.
