Great price for a useful little device. Just what we needed to check inside the walls of a new extension we have had. We wanted to check that the builder had put the correct insulation inside due to other issues and very pleased to see he had. This has given us peace of mind and didn’t cost an arm and a leg to find out. The very long camera is super flexible and easy to poke into the smallest hole, the app is simple to navigate and there is a button on the cable to change brightness. For the price a bargain. This could be used for many issues in cars etc where you can’t get in easily. Really happy thanks this was a big help.

The picture quality was way better than I was expecting. I hope it last awhile, this is a really cool tool.

Great quality

Very easy to use

Article was delivered very quickly and neatly, article then times taken in inspection. Was actually already mounted everything, memory card was inserted, endoscope already mounted and accessories such as Imbussschllüssel small spare screw in a small plastic bag available.
Switched on, battery and was almost to good 100 percent loaded----- thus immediately ready for use, endoscope actually very rigid and the function of the LEDs as it advertised or advertised. The side LEDs can only be activated as well as the camera switching to the left / right view, by pressing the small push button on the endoscope (USB port on the camera). Screen provided with protective film and everything in an associated case well and safely to store or protect available.
Image quality for close-ups acceptable to good, editing options but to be qualitatively better .... there you can about an image editing program still rausholt so some (but is not a point of criticism for me, just a note) ....for the quick snapshot, inspection / examination or short video sequences but quite sufficient.
USB - connection to the camera with a small screw fixed, has its reason because the cable is a little rigid, it protects the connection in the camera from accidental loosening or breakage. The small support foot, which can be attached to the camera, is well-intentioned but somehow not mature, unless you no longer move the endoscope cable because otherwise the camera actually does what it wants.....slides back and forth or falls down if necessary.
Settings of the camera such as date, time, language, etc. quickly and intuitively adjustable. Manual available .....
You should take the time to check all functions and familiarize yourself with the camera. If questions arise, the customer service provides very fast and friendly support in a short time .....Klasse
Should the quality and customer service remain so, which I hope, the camera is for me a clear buy recommendation.

Sanitation issue in RV. It worked well.

After charging the battery it works flawless and has a great image, the video cable is stiff enough to work it around corners. Delivery came as predicted by seller.

K&F Concept endoscope camera. With a cable length of about 5 meters, this is aimed at semi-professional users, typical areas of use would be, for example, the examination of pipes, cavities in vehicles, hard-to-reach places in shafts or, as in my case, the inspection of a pellet silo.

Qualitatively, the endoscope makes a really high-quality impression, is heavy and very solidly built, even the supplied case could also be considered for professional users. The scope of delivery includes the case, the endoscope, the probe incl. 5 meter cable, an SD card with 32 GB, two holders and a clear manual.

Here are the specifications according to the article description:
- 4.3-inch color screen
- Resolution video:1280x720
- Photo resolution:1920x1080
- The probe is waterproof according to IP67 standard
- Probe diameter 5.5 mm
- Memory of the included SD card: 32GB (for photos/video recording)
- Battery memory 2600mAh (lithium battery)
- The probe has 8 LED lights

I've had the in use a few times now and can mention the following punks:
- The battery was almost fully charged on delivery, there is a USB Type-C charging cable included, but no charger per se. However, that is not a big deal - any USB charger can be used for this. So far, I have not managed to empty the battery in my few uses, so I cannot make a statement about the runtime yet.
- The endoscope cable is a bit stiff at first, but after unwinding it can be bent well into shape. However, you should not expect a 90° bend, it is definitely too tight for that. Insertion into e.g. empty tubes is a bit tricky, the cable holds its shape, but then adapts to bends in case of resistance. Here, as I said, some practice is necessary at the beginning. Ideally, you do the insertion in pairs, so one person can insert the cable, a second then holds the screen. Since it is IP67 rated, the cable could also be provided with a lubricant, e.g. soap or similar, to reduce frictional resistance.
- The lens head is a bit large with just under 5.5 mm, so it can be a bit tight at drain openings, for example. At our sink, I could not insert the head through the drain grate, I had to remove the siphon and then insert the cable over it.
- The front camera is designed for distances of max. 10 cm, the side cameras for max. 3 cm, that's enough for pipes and cavities, when checking my pellet silo is then due to the size of the image a little blurry, but it is perfectly sufficient to visually check the level, for example.
- The LEDs in the endoscope head make good light, even the darkest pipes are illuminated and you can see the surroundings well on the display. Unfortunately, the image quality is somewhat sobering when viewing the recordings on a PC, for example, despite Full HD photos and HD Ready videos.
- Nice feature: the scope of delivery also includes a hook and a magnet to fish out keys, screws, etc. from pipes.

Conclusion: It's a very robust device, which fulfills its tasks. I lack the comparison to other devices, but I am satisfied so far. The quality of the stored pictures and videos could have been better, but are still ok. I would give 4.5 stars, but then round up to 5 stars.

for diagnosis of engines

I was provided the item free of charge for a test, but this fact is not reflected in my reviews. If something is no good, then I write it that way.

Everything you need to get started right away is included in this kit. The device and all the accessories come in a small plastic case. With some devices, there is sometimes the problem that once unpacked, it does not fit back into the case. In this case, however, everything can be conveniently stored again without problems, the space for this is more than generously designed.
The main part houses the 4.3-inch color screen and the controls. The whole thing is very robust and also feels valuable. The controls are easily accessible and also respond very well to pressure. Operating the device is no problem with them. I only had no success with switching cameras in the various menus at the beginning. These are self-explanatory and clear, but switching here was not possible. Even in the (not exactly extensive) manual was nothing to find about it. After a long search, I found the button: It is located directly on top of the connector that connects the optics to the device. This connects to the top right and is about 5m long. It is relatively stiff, but it can be maneuvered well in tight spaces. The image quality of all three cameras is good, and the lighting is also bright enough to make even small details visible, but not so bright that when you are closer to an object, it can then only be seen as a white spot.
The scope of delivery also includes an SD card. With 32GB, it is also big enough to store lots of photos or videos on it.
It is powered by a built-in battery, so the whole thing can be used very flexibly, so you do not necessarily have to have a power outlet nearby. The battery can be recharged via USB-C plug, and the cable for this is also included.
Furthermore, two tool tips are included, which can be attached to the camera. This is very practical when, for example, dirt has to be removed in order to inspect the material underneath.

All in all, everything you need is supplied here for about 140€ (as of 04/22), and that too in excellent quality.
