Hello everyone, this product is a long-range binocular from the K&F brand. I really liked them because they are compact but have excellent sharpness even at the maximum viewing distance (1000m). They are made from high quality materials that feel quite resilient to the touch, but should be avoided at all costs as it would damage the lens mechanism. They have IP65 protection against splashes and dust, of course, in no case should we immerse them in liquids, because this level of protection does not reach this level of protection. They come with a case and a strap to wear around the neck. A special cloth to clean the lenses without scratching them is also included and a very well explained manual in several languages including Spanish. The truth is that the image that can be seen through these binoculars is quite sharp, much better than what I've been able to see through others I've used before. The colors are quite natural, not too opaque or too saturated. The approaches are made easy, you don't need to be an expert to clearly see what you want. My son and I really enjoyed using them so I recommend them.
