My first endoscope and I'm totally happy. I think it's a great device with many possible uses for the hobby area. As a hobby mechanic on cars, I can now find lost small parts in the built-in engine compartment without jacking up the vehicle and removing the annoying underpanels. I can finally take a first look at my engines without removing the cylinder head. The camera quality is sufficient to even recognize the cross-hatch and larger grooves in the cylinder wall. The valve seat and the valves of a 1.3 liter engine are also easy to inspect. I can then transfer the images and videos stored on the memory card supplied to my PC and process them there. For this I needed an adapter for the corresponding memory card connection on the PC.
The only small disadvantage is the back of the camera body. Since the different diameters of the camera housing and the cable create a small step, the camera gets stuck there, for example when it is pulled back through the spark plug shaft from the combustion chamber. I wrapped the area with electrical tape to create a slant there so it wouldn't get caught anywhere when the camera was pulled back.
Conclusion: great value for money! Meets and exceeds all of my expectations. Would I buy again!

Must check gutter. Insulation pipe and bend taken by the electrician.
Camera plugged through. The camera looked out about 3 cm at the front of the pipe bend.
Skylight opened and camera with tube pushed over the roof to the gutter.
No kinking of the 5m long camera line. No fumbling around when pushing over.
perfect picture. Pipe rotated 180 degrees with camera and checked the other side of the gutter.
Everything perfect.

During the last heavy rains, water ran into our basement. I then suspected a rainwater downpipe that runs inside a house wall and weighed it up: buy it or have someone come directly with equipment? In the latter case, 200€ are quickly gone with the journey, as I had to find out myself.
I then decided on this device with a dual camera, which, as you can see from the example image, was the right decision. Of course, you can't control exactly where the camera head is, which is precisely why the dual camera is helpful, because by rotating the cable you get something more in focus with the side camera than with the front camera.
You should actually always activate the video recording immediately, because in case of doubt you can record places in between that you can no longer reach / focus on afterwards. The videos are saved uncompressed, which is not a problem at first since the memory card is large enough. If you want to send the videos, you should then compress them afterwards with common tools.
Sure, it's not a professional device and the image quality on a large screen is only moderate. But you can't expect more in this price range. But it is enough, for example, in the event of a pipe burst, to get an initial picture of the problem and then to see where the problem lies and whether the professional has to come or not.
Of course, I can't say anything about durability yet. Anyone who has to use something like this on a daily basis is more likely to buy a device in the middle three-digit range.
All in all I am very satisfied and give a clear purchase recommendation!

The shipping and packaging from Kentfaith is top notch as always.

The endoscope camera from K&F Concept is just right. I had to run a LAN cable through the tube from my 1st floor to the ground floor and couldn't get through. This is very annoying because I have no other way from top to bottom. With this camera I found the problem and fixed it. The image quality and the light were just awesome and everything is just right. The processing and the quality of the device is P/L technically top. When using it, I noticed something that you have to take care of the device. I'll get a bracket for it or the manufacturer could install a magnet if the built-in technology allows it. The connection of the camera is connected to the housing with a locking system > TOP. The hose is also correspondingly very rigid, so that it can also cross any obstacle without any problems. The charging cable is included in the scope of delivery. The power pack is not on board for this. Nevertheless, I can recommend the endoscope camera with 2 lenses

I decided on this device because I often have to work in a dirty and oily environment during repairs and therefore don't want to use my cell phone for evaluation. The operation is very simple and self-explanatory, just switch it on and click through the menu. It can be switched to German and everything that can be set where is understandable. The device can also be easily operated with gloves. The autofocus works well and the brightness of the two cameras can be continuously adjusted using the wheel at the top right, so one hand can guide the camera and the other can operate the display. Photos/videos can be made quickly and easily at any time at the push of a button. Switching between front and side camera or both can also be selected at the direct push of a button, also the mirroring to turn the writing the right way round. Accessories such as magnet, memory card and USB cable are included. The battery was half full after delivery so the device could be tested immediately after delivery. I am completely satisfied with the endoscope camera and can recommend it without reservation.

Great product! Suitable for the inspection of combustion chambers. The minimum distance to get a sharp picture is 5cm, but even at 2-3cm it's still sharp!
SD card included. Photo and video function. Very narrow, only a few mm. You can get anywhere there. The housing edges of the camera part are somewhat unfavorable. Due to the angular cylindrical structure, you quickly get stuck. Especially when pulling out. That could be rounder. Otherwise: value for money

Great HD images. Use it for MX in my cars and planes. The pictures are from a Volvo engine. The Ralcam scope is very easy to use. Arrived with a charge that lasted about 30 minutes on/off.

This endoscope is actually not comparable with the usual devices. The most obvious and biggest difference to other (cheaper) endoscopes is the movable camera (see video). If you actually want to look into a more complex cavity, this is just absolutely brilliant, no comparison to the normal devices.

I've been doing everything on my car myself for years, now I've gotten to the point where I can't get anywhere with my normal endoscope camera. It is incredibly helpful, especially when examining the cylinders.

I actually haven't found anything negative with the camera yet, everything is exactly as described on the product page:
- Large and really good display
- semi-rigid camera cable
- 10 meter cable length (so far always sufficient)
- reputable manufacturer
- SD card included
- Charging via USB-C
- Multilingual menu
- Very bright LED illumination
- Temperature sensor at the top
- Not dependent on cell phone or apps due to internal display
- Good camera

A big extra that is not mentioned in the description:
The device has WLAN. You can connect your smartphone super easy wirelessly (the app for the iPhone is called "AllScope"). The functions include, among other things, a live image transmission and that recordings can be viewed and saved directly without a PC on the cell phone (see screenshot).

The endoscope camera from K&F Concept can be flexibly rotated through angle and can thus shoot live images from otherwise completely inaccessible places. Water resistance is at the top of the list of requirements here. With IP67, the 4.3-inch camera also masters water resistance with flying colors.

The 8 LED lights ensure that the waterproof tube camera (IP67) brings a well-lit video image to light.

The price of just under 300 euros (as of September 4, 2022: 169.99 euros) is certainly steep at first glance, but once you've had the endoscope camera from K&F Concept in use, you'll save so much valuable time that the purchase will quickly pay for itself.

For example, if you have a small business and regularly have to carry out repairs on equipment that is very difficult to access, you will really enjoy this endoscope camera from K&F Concept.
