At visibly already it appears that the diameter of the objectives of these binoculars is less than 100 mm, which also confirm its dimensions: 230x195x75 mm. Indeed, 75 mm corresponding to the thickness larger, therefore aim rimmed metal, it can therefore be 100 mm otherwise we had a thickness of 105 mm. It is concluded that the 75 mm therefore corresponds to a 70 mm lens circled only. This breadth of false target is also true in the width binoculars, only 230 mm. Indeed the two circled goals by 105 mm diameter each, the two side by side should amount to 210 mm and it should be a gap of 20 mm between them (for 230 -201 = 20). Or visibly although there is seen a far greater gap than 20 mm, since it actually 230 -75 to 75 = 80 mm. These binoculars are therefore a scam Amazon and commit a crime of complicity scam by selling them. As to the alleged magnification of 180, there also is beginning to suspect a scam because it has never seen, the maximum zoom magnification is 9 times the minimum magnification that is 20 on this model. Rather they would favor a multiplier of 5 or is a magnification of 100 to 120 ...
