The binoculars were a waste of money .Electronics have spoiled us and these manual binoculars can't compare. Based on my observations, the image quality was poor and they were not easy to focus. The multi-layer coating for anti-fog didnt work and I had to stop multiple times to wipe them down. The pros are that the binoculars were lightweight. The cons are that they lacked the features that we have come to expect from electronics..
