The design of the monocular is quite successful. It lies well and securely in the hand, it is easy to transport and can also be operated very easily. The workmanship of the monocular is also convincing so far. Of course, you immediately notice that you are not holding a high-end device with high precision, which can easily cost 10 times the price of the monocular reviewed here, but rather a mass-produced model. In my opinion, however, it would be wrong to expect anything else, and this monocular is quite solidly manufactured on its own. As for the performance of the monocular, I'm a bit ambivalent. In principle, it delivers a decent image and a usable magnification, but I have serious doubts as to whether the magnification is actually as high as stated in the product description. The difference to high-quality binoculars and monoculars with high-quality, precisely manufactured lenses is also most evident when using the monocular (of course). There is no question that this monocular is suitable for "woods and meadows" use in the hobby area, but if you want to do more serious nature observation etc., you should invest in something of higher quality. The smartphone holder is still more of a gimmick. This monocular is currently priced at around 40 euros - in principle a cheap price, for which a fundamentally fair equivalent is offered here. All in all: for occasional use when hiking etc. this is a nice monocular and if you don't have too high demands you will certainly be happy with this. However, if you are more interested in observing nature or animals or would like to take enlarged pictures with your cell phone, you should probably invest in a higher-quality and higher-priced model. I get a total of almost 4 stars.
