I first acquired a pair of binoculars first prize and I was a little disappointed because not very bright. This pair of 10x42 binoculars is very bright and the picture is clear. The optical quality is good, the sharp image and the product seems robust. Not very heavy and compact. What more? I recommend this product whose price is affordable for such quality. A small downside to the bag that is a little light in the material used but this is a detail.
