He loves it

The endoscope camera from K&F Concept really surprised me in a positive way. As a hobbyist, I was looking for a practical tool to examine hard-to-reach areas more closely. And this endoscope has my compatibility with my iPhone was an important aspect for me and I am glad that this endoscope is designed specifically for iOS devices. Setup was incredibly easy - all I had to do was download the app and connect the endoscope to my iPhone. Within a few minutes I was ready to use, almost plug and play. The 5 meter long semi-rigid cable proved to be extremely practical. It's long enough to get into tight and twisty areas, and the semi-rigid material allows the cable to be bent into different shapes to achieve your desired viewing angle. I was impressed by the flexibility and stability of the cable. The image quality is also very good. The camera has a diameter of just 7.9 mm, which makes it possible to navigate even in the tightest of spaces. The 8 LED lights provide sufficient illumination so that I was able to capture clear and easily visible images and videos. The IP68 waterproof rating was an added bonus and even allowed me to perform inspections in humid environments. The included app offers a variety of features including adjusting brightness and contrast, taking photos and videos, and live streaming the image to my iPhone. The operation is intuitive and user-friendly.

It's very interesting to be able to crawl into corners with a camera like this that you wouldn't normally be able to reach. Be it to find something or to investigate a problem in more detail. I think a full 5 meters length should be enough for almost all purposes. Of course it becomes difficult to control the direction of the camera the further away it is, at some point it will only move in one direction. The lens is significantly shorter than on another endoscope I ordered, which makes it easier or even possible to get around the curve in some corners without getting stuck. It's really plug and play - plug it in, download the app and the image is there, that's how it should be. The image quality is completely sufficient for my purposes and the LEDs at the front are super helpful, as the corners to be examined are rarely well lit. You should keep in mind that the camera only works for IOS with Lightning - if the new iPhones soon have USB-C you would have to buy an adapter if that is even possible.

Update: great device. To get it to work with my phone I had to enable
OTG. On my phone one opens settings, then additional settings, and OTG is low on the screen
Company tech support walked me through the process. You can reach them through Amazon

First look here. I downloaded the required app on my phone and tablet. Works on my Lenovo tablet. Does not work at all on my N30 Nord with Android 13. Device will not connect to the phone. This limits the utility, but not completely.

I really like this.
I have a loose cable camera but it has to be held where I want it to be.
Good in done situations but not perfect
This camera has a semi rigid cable so I can shape it as needed and take a look
Great for inside walls, soffits, engine cylinder walls, with the mirror cylinder heads/valves and tight spots where you can feel what you touch but can't see. You can hook it and pull up the item
Really great to have in the service truck.

It's a great product and easy to use.

As far as the image quality is concerned, I'm quite pleasantly surprised. Often enough, such cameras only have a resolution of VGA, so the photos end up in the memory with 1920x1440 pixels - absolutely sufficient! The camera has already been used several times, one of which was under a server rack, where the classic thing actually happened: there was a small screw from a slot plate underneath. A second assignment was the inspection of a completely wild opening in the wall, through which a whole bunch of various cables ran. This breakthrough is located directly under the ceiling and is therefore difficult to reach without aids - see the attached video. In my opinion, the camera does a surprisingly good job - even in teamwork with the app, which comes with no frills. The areas of application are extremely diverse, including in the area of water/wastewater/rainwater I clearly see this camera as a good problem spot analyst. With a diameter of just under 8mm, the camera is really small enough to fit pretty much anywhere. I find this camera - and especially with this battery-free design - more than practical, as it is ready to use anytime and anywhere. The image quality is surprisingly good for inspections in various low-light corners, so I simply can't fault it. In my opinion, the price is far more than fair, I would even pay a tenner more for it and for the quality delivered - purely out of belief in the product. In the end, I'm absolutely happy to give this helper in an emergency 5 stars because, in my opinion, everything in the product promise is kept and a few expectations were even exceeded. I therefore see this camera as an all-round honest product and recommend it without reservation.

As soon as I opened the package I thought it would be a mess to use, but once you download the application, connect it to your mobile and... done! brilliant! I have an iPhone and most of the time I plug something in, it's a roll, but this was quick and without any problems. It has an adjustable light that allows you to better adjust the image and it has a very long cable. Very useful for seeing where your eyes can't see, for example workshop equipment or even pipes and the like. On the negative side, I noticed that the light got quite hot, I assume it's not recommended for prolonged use, and that when you take a picture it doesn't save directly to your gallery but to the application , then save it as soon as you enter the application. I've already told you that I was surprised at how easy it is to use and how much time we spend laughing under the sofa with the camera. Recommended!

I loved it, professional tool. Thin enough to fit into the smallest car openings. Excellent

I bought this for the semi-rigid design. Other than trying it to make certain it worked on arrival, I haven't used it yet. My son-in-law tried it and said it worked well for checking wiring in his walls.

The software is clunky and seems to be proprietary, but I can live with that.
