I tend to view these mobile phone lens adapters as gimmicky plasticy junk that just sits in a drawer somewhere after being used exactly once... 9 times out of 10 that is the case. Not this time! This cool device essentially turns your phone camera into a digital microscope. The addition of a ring light around the lens is crucial here and the execution is well thought out. The ring light enables your subject to be in full light even when the lens is literally sitting on top of the object you are viewing. I used a piece of cloth as an example. The first image is at the standard 1x from my Pixel 8 Pro. The second image is using the same 1x camera on my phone but with this 150x lens adapter in front of it. The results are insane and totally unexpected! I can't wait to try this lens out on more objects around my home. Highly impressed! 5/5

This mobile phone holder which utilizes a neckband concept is very effective for using a smaller mobile phone to take point of view videos. Because it rests on your neck and is part of adjustments your body automatically makes while moving It creates a surprisingly stable video. It uses a clamp to hold the video device. Has a variety of adjustments so there should be no problem getting it into the position you want. Everything seems very rugged and well made, and I'm planning on using this to take some content videos while riding on my motorcycle.

⭐⭐⭐⭐The K&F Concept 4 in 1 tripod comes in a practical nylon bag with instructions, a mobile phone holder, two Allen keys and a release remote control. The tripod consists almost entirely of metal and some plastic (e.g. feet, casing, etc.) . The workmanship is impeccable and the tripod appears robust and of high quality. The remote control and the mobile phone holder are made of plastic and are nothing special - but they work perfectly. The functions of the tripod do not need to be explained here, but everything works perfectly and so does the tripod We find it very good that it can be used as a monopod or extendable selfie stick. The tripod is extended and fixed by turning the individual segments. A lock symbol (open/closed) symbolizes whether locked or not. Some users criticize this. We think it's good because you can quickly lengthen or shorten/retract the legs etc. When folded up, the tripod is also very compact, quite light and can be taken anywhere. Of course you make compromises with the rather small ball head, which might just be too small for the 4000€ full-frame camera, but that's not what the part is designed for, but for mobile phones, action cams, small MFT/APS-C cameras & Co. - yes, and the tripod is more than enough for that.We used a smartphone and an action camera with the tripod and it worked perfectly.Overall we are very satisfied with the product for the price and can recommend it!⭐⭐⭐⭐

This small tripod packs a punch with some pretty nice feature. The mobile phone holder paired with the bluetooth shutter switch is nice. Also easily supports a DSLR or full body camera.

The filter holder would be better if there was a fixing screw for the rotating ring. Otherwise very good.

The K&F Concept 4 in 1 tripod, 170cm mobile phone tripod camera, eccentric tube selfie stick, flexible, lightweight DSLR tripod, E224A3+BH-18 black (black) is well made and functional.

It is very neatly processed and has a remote control in a holder on the stick that you can connect via Bluetooth, which is easy.

In addition, the handle can also be unfolded into a tripod base, which further expands the possible uses.

The holder for the smartphone is stable and secure, you can also swivel it 90 degrees.

Conclusion: 5 stars from me

We unpacked the 10-30x50 telescope and found everything as described. The hand tripod and the mobile phone holder are made of plastic. The very light tripod has a stable ball head and is sufficiently stable. It should, too, if you want to attach your cell phone and the holder to it. The table tripod alone is quite useful. The mobile phone holder is more of a gimmick that we would not use in practice. It takes a relatively long time before we had attached and aligned the mobile phone together with the holder on the telescope. The picture that you get on your cell phone is very difficult to focus on. Due to the distance between the optics, the image naturally has wide vignetting and can only be seen as a small circle. We have not yet been able to get a photo image like in the advertisement with a mobile phone holder on a telescope. As with all mounts of this type, the whole construction is very sensitive to touch. The telescope itself makes a good impression. It is robustly built and feels good in the hand. Settings run smoothly and evenly. Once positions have been set, they don't change so easily by themselves when you carry them around. The image sharpness is satisfactory in every zoom range. Two rubber caps are included to protect the optics. They fit their positions tightly. Conclusion: Robust and handy telescope. weatherproof (No rain has penetrated) Good optical properties. Sharpness and zoom settings work well.

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.
