The optics are really excellent (light, precise). The front covers fall as soon as one tilts the binoculars. The focal adjustment knob is a bit long and inflexible to rotate, preventing rapid development (a problem when following a moving subject). The setting catch diopter can be adjusted exactly to 0 (a little or a little + -) and this is a real concern for the sharpness because I have no difference between my eyes, why impose a notch? The size is correct for x10. Fixing the rubber eyecups hardly inspiring. The cache of eyelets is not connected with binoculars. In short, the quality of binoculars is not up to the glasses and certainly does not deserve the # 1 ranking awarded by juries ... under influence of advertisers.
NB: Unlike 2014 clients, my shipment (January 2015) contained no accessory (or harness, nor housing nor wipe ...). Do not worry as this is consistent with the description, but do not expect either Christmas either.
