Hello. The scope is good for the price. Of course, there are blurry edges, but that should be manageable for the price. The sharpness in the center and extended center is satisfactory to good. If you then switch on the 2* zoom of the smartphone, you get a format-filling picture with great imaging performance (see pictures).

I'm curious to see how the imaging performance of the monocular will fare when it comes to stars tonight. If necessary, I will then expand the review.

So far: processing and imaging performance are excellent - especially for the price

Addendum: Good for astronomical observations. Very sharp picture. Moon craters clearly visible. Stars are shown as points. Orion Nebula easy to see because it is bright. However: very susceptible to bright backlighting with pronounced ghosting.

Recommendation!

This monocular has a comfortable weight, so that your hand/arm does not tire as quickly, even after long periods of use. In addition, the loop that can be attached to the side makes it very comfortable to hold.

The magnification works perfectly, I consider the workmanship of the entire device to be of high quality and very good. As a person who wears glasses, I can use the monocular without any problems. In my opinion, the holder for the smartphone does fall off a bit. That makes a pretty cheap impression and is only placed on the front of the monocular. That wobbles properly. Nevertheless, I managed to take really great close-ups with my smartphone and the monocular. I really liked that. However, I recommend everyone to work with a tripod in any case, as you simply cannot hold your hand so still that the images do not shake even when you have zoomed in closely.

I think it's a shame that the attachment for the smartphone doesn't fit in the bag. With the monocular in there, there's no room for anything else. And now? If the part flies around loosely in the area - that actually annoys me quite a bit, hence a star deduction.

Well... of course it's not an Eschenbach or even a Carl-Zeiss device for a 4-digit amount... but to be honest, for 26 euros including shipping, I wouldn't have expected that this part would bring you such a great, clear view.. I wouldn't subscribe to the exact details of the zoom factor... but the zoom works seamlessly and perfectly and a clear image can be set perfectly in every zoom position on the front adjustment wheel. The operation is child's play... Whoever writes here that he is sending the thing back because it cannot be sharpened has, in my opinion, caught a fairly low intelligence quotient or a defective device. I took the 3 pictures with my Samsung Galaxy Z Flip 3 without a cell phone holder, just holding it in front of me (therefore a little blurred). The first picture is without monocular.
Absolute purchase recommendation for amateur hobby area. The thing is fun at the lake, in the forest, on the mountain or even in a high-rise building...

The telescope delivers a sharp image and is easy to use thanks to the focus adjustment wheel. A thread allows connection to a tripod, so that a steady picture is possible. The close-up setting is sensational, as it enables small animals such as frogs or dragonflies to be observed very closely. These can then also be photographed using a mobile phone with an adapter.

Very happy with this product. The picture shows how I used/tested it for the first time. I haven't taken my kids on holiday or for a walk yet, I think they will enjoy playing with it. You never know when it might come in handy later in life... it's cool to have. :)

Discreet quality. Good given the price. Not very wide field of view and brightness that decreases as the zoom increases. But that's physics and not even Swarovski, Leica or Zeiss could do anything about it. However, it is light and compact to put in the backpack.
While it can be used “on the fly” without support at 10x, at least 2 hands supporting the elbows must be used at up to 30x.

I acquired this monocular to use when we do mountain routes and although my daughter wanted to use it, the truth is that we want to use it everything because it is very light and comfortable to carry in the hand. The vision it offers with its 12x50 magnification is really surprising for its sharpness even in low light.
It has a wheel at the top to adjust the sharpness of the image depending on the distance the lens is at. At the end of the monocular, where we approach the eye to look, it also has a wheel to increase or decrease the field of view. Comes with a holder to attach it to your phone so you can take photos or videos. It also includes a carrying case, a cleaning cloth to clean the lenses and covers to protect them from possible scratches or bumps.

Compact but super powerful crystal clear monocular for a serious hiker or an outdoor adventure seeker. It's always important for me to have handy binoculars or monoculars nearby to take an exceptional look at nature and our oceans and mountains. Also great for bird watching and sporting events.
K&F Concept has done it with this very affordable monocular right here. This is 10-30x40 means not only can you see the object brightly and clearly, but you can also use the zoom function. With my years of experience with binoculars and monoculars, I'd like to suggest that if you're going over anything over seven power, it's better to use a tripod. Most people blame monocular, but it's actually their hands/body movement (nothing wrong with the product) This monocular comes with excellent built-in tripod screw function. Please see all my pictures and decide for yourself.
Also, I would like to point out that the lens is 40mm with a perfect 20mm eye lens. Even when the sun goes down, you can have a wonderful view because of the larger size of the objective lens. It will take a few times to perfectly open the monocular but it is to be expected from such a wonderful product. Enjoy the sightseeing!!!
PLEASE NOTE: Tripod is not included, but it will fit any tripod. The zoom image I took is only at 10 power. It's my cell phone picture nothing fancy. Amazing right!

My daughter tried this out on her phone yesterday and is blown away by some of the pictures! I think they might be better than mine with a zoom camera but haven't seen them on a computer yet. Immediacy is key in her eyes so she can share it. It is now firmly attached to the phone jack and she managed this on the cliffs in high winds. She found it easy to use.

Since my old binoculars were no longer up to date, I decided on this monocular.
The scope of delivery includes the monocular, a bag, cleaning cloths and instructions.

Like many others here, I couldn't focus the monocular at the beginning. But if you take a look at the instructions, it quickly becomes clear why this is the case.
Followed the instructions step by step, the monocular could be focused and shows a really great picture.
Especially with a discount I can only warmly recommend it to you.
