I was able to use this camera attachment on my Celeston 10x50 Outlander and Barska 20x80 and is fits perfect and snug on both binoculars. The little camera is adjustable as far as fitment on your eyepiece.The app is very easy to use and you get to view the binoculars live on your phone. It connected to my android phone right away and the performance and functionality is smooth. You can then take captures of what you are viewing or record it as video. The quality depends on the focus, clarity and what you are viewing. Overall I am very happy with this little camera and for the price I think it is worth having.

We have an annual pitch on a campsite by a large lake. Eagles can regularly be seen in the sky here, which I like to observe with binoculars. However, it is exhausting to keep the binoculars steady for a long time. That's why I ordered this tripod.

To attach the binoculars to the tripod, I bought a binocular tripod adapter. Thanks to the common thread, this can be attached very well and I can then also use my binoculars on it.

The tripod has a ball head in the upper area that can be tightened. If you loosen it a little, I can turn the binoculars in all directions, don't get cramps in my arms and can watch the eagles wonderfully.

But I also like to use it for my camera and if you have an adapter for a mobile phone, you can also attach it to the tripod. So it can be used in many ways.

What I really like are the adjustable feet. A spirit level is also attached to the tripod so that you can set it up straight. In addition, it can be extended up to 2m and has a comfortable height to work with.

Very well made, stable, can be extended far and, thanks to the attached spirit level and adjustable feet, it can also be placed horizontally. I like it very much... 5 stars

I have just been using these as night vision binoculars instead of strapping it to my head, so I have no idea how the head straps feel.

It takes about two seconds to get started with this. It charges via USB-C, so you can just plug it into your cell phone charger. Then you just either turn it on and start looking, or first insert the included 32gb Micro-SD card if you want to record something. You can adjust the brightness of the IR light with one button. There is one dial for focusing, and it's on the left lens.

The picture is extremely crisp. I'm fairly certain I see better through these, in pitch black, than I do with my eyes in the middle of the day. I can count the whiskers on my cat from 20 feet away in complete darkness. He definitely sees me, due to the red light that comes out of the IR light. So...maybe don't go staring at tigers.

Battery life seems pretty good. I've been playing around with it quite a bit and have yet to kill it. Plus, I just plug it into any of the roughly 15 cell phone chargers that a scattered all over my house when I'm done with it.

The K&F Concept 10-30x50 HD monocular telescope arrives securely packaged. Everything smells pretty chemical, the smell seems to have spread from the bag to everything else. The monocular makes a handy, robust impression. The colors are muted, the surface is non-slip and the magnification settings are easy to use. The enlarged image is clear, although it feels slightly tinted. So it can be used as binoculars. The points of criticism refer to the use with the mobile phone. The tripod is valuable and stable, with a little patience you can find a stable combination with cell phone and monocular without the tripod tipping over. The mobile phone holder is made of plastic, when it is pulled out to adapt to the width of the mobile phone it squeaks and ratchets, the light padding doesn't help there either. The main problem is the interaction of holder, monocular and mobile phone. First you have to position the hole in the bracket over one of the camera lenses that are now available several times. Then the monocular is attached. However, since this has a weight of a good 350 grams, it pulls the holder away from the camera lens and the resulting gap means that you can no longer get a clean photo. So for a good result you have to stabilize the monocular with one hand and use the cell phone/the shutter release with the other. This takes time, patience and a steady hand. This is nothing for a quick snapshot. In addition, without a mobile phone camera zoom, you only get a small round section enlarged, you only get a full picture with zoom and then the photo quickly becomes shaky and blurred. For a meaningful use with the smartphone, a more stable mobile phone holder would be necessary, which can counteract the weight of the monocular. In any case, with a Samsung A 70, the results were disappointing.

Love this little tripod. I’ve used with my cell phone, my GoPro hero 3, and a pair of binoculars. Bendable legs so a variety of uses and also great in small areas.

I am impressed by the quality of the monocular binoculars. It lies well in the hand, the dial is smooth-running and can be operated with one hand. I would actually give 5 stars for that.
In my opinion, the included mobile phone clip is useless. The clip itself is very strong and once you attach it, it sits securely on the phone. Unfortunately, the same cannot be said of the rest. In order to place the monocular reasonably securely on the device, you have to hold both devices and then have no free hand for image settings and shutter release. With a tripod - a corresponding thread is available - I have not tried it. That might free up a hand. However, the basic problem lies in the fixed distance between the photo lens of the smartphone and the monocular. Maybe it's me, but I only get blurry images in circular shape with it.

Really good quality m42 lens adapter, made of metal. Perfect grafts.

These are good binoculars to have around. The weight is easily manageable and the optics are good! They feel good in the hand and focus is easily accomplished. I love the clear view!
I included a picture taken with my phone and it is followed by the view without extra optics. I actually think the phone pictures will improve as I get used to the objective! Eyes through the lens are much clearer, but I can't make a picture of that.
All in all, I think these are great binoculars!
