The magnification range of 8x to 24x is quite decent. Logically, one can no longer maintain the image at the large magnifications quiet. In a twenty-fold magnification you have to naturally lean, if one desires a shake-free image.
With the operation I had no problems. And there are not a lot: eye relief; Diopter correction; Focus Magnification. Done. If everything goes perfectly.
What makes the binoculars so special, is the crystal-clear optics that delivers sharp images with good brightness. Such a thing has its price, but which is quite ambitious.
Conclusion: Overall a very good, small pair of binoculars with a strong finish.
