There are cheaper and more expensive monoculars. Since I only want to use the monocular occasionally, I didn't want to spend too much money. That's why I first ordered one with similar features to this one, but about 20 euros cheaper - and immediately returned it because of the extremely toxic-smelling plastic casing. Then I looked around again and came across this monocular from K&F, at around €45 it was considerably more expensive than the first, but still cheap compared to other devices. And this time I was not disappointed. Not only does the material here not emit an odor, it also appears to be of much higher quality overall. Image & magnification are completely fine for me. And the mobile phone holder is also very practical: for the photo of the moon I used a slightly older smartphone (digital zoom only) and mounted the monocular on a tripod. I removed the hand strap again because it did not fit the monocular properly in the supplied bag. That's a shame, a few millimeters more air would have been sufficient. It is also a pity that the lid of the outer part, in the opposite direction to the lens, is not connected to the housing and therefore always has to be stored in a storage bag. jacket/trouser pocket during use Conclusion: the price-performance ratio is correct, purchase recommendation!
