I had tested a total of 3 times Monocular.
I'm gone to the reviews on Amazon. Priced lay the monocular of about 9-24 Euro.
What I would write now, however, everything is already explained in the video.
However, it was a bit difficult to take the display of the distance to the camera.
The advantages of this monocular are the price. What is less good, the weight and you can not adjust the sharpness.
But what do you expect more for just under 9 Euro.
