We just love this binoculars!

Exselent Poenter, my first meteor piece was found, Highly reqomended.

They are brilliant, I can see so much from this, the conclusion is excellent, really well done, would recommend to anyone.

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!

During the window test, when we set ND to the maximum value, I didn't notice X.

The filter does not alter the coulUKrs and there are no rare vignettes (the famous X). It has a stop at minimum and maximum and markings to fix the intensity, even at maximum there is no vignetting. The filter is not very big, but it is better to put the lens hood on the lens first.

Does leave a noticeable pattern near maximum darkness. From 0% to about 80% it's clean, but above 80% light reduction it will quickly become rather unusable. At 90%, it does become very obvious.

These binoculars are brilliant.
