My copy is likely to be well adjusted, it forms sharply and the stars are punk-shaped.
During the day I do not see any difference to 8x40, which is quite clear, as the pupil expands only in the dark. At night, then displays the difference.
Initially I was skeptical because of the background fill in lichtverseuchtem night sky, but the faint stars and star clusters also emit a little brighter and stand out well against the sky brightened. The comparative test of 10x50 was perhaps better of the separation sky / object a nuance, but this advantage was compensated by the significantly stronger wobble. For me, the 8x magnification is the maximum, so that the image is not too much dancing in front of the eyes.
Mechanical likes it I also, the eyecups are made of strong hard rubber and can be pulled out far, I like that because I like to bring the lenses at less distance (eg with my Olympus) the eye to start, which is troublesome.
The weight, balance, in connection with the grip, are balanced.
The bag is very soft, I have found me why a camera bag.
Thus, I am satisfied, although I may be the 7mm exit pupil is unable to make fullest because advanced age. It fits comfortably in your hand and shows the faint stars, and deep sky objects, a little clearer than my 8x40. However, the difference is small, if it were not also waterproof and fog-free, the charge would not have been justified.
