I bought it to look into aircraft engines and have used it twice so far. The image quality is good and easy to use! Definitely recommend if you are looking for one!

The device does what it is supposed to do and in absolutely sufficient quality.
The function to create pictures and videos is a nice feature which makes it possible to share the results here. The gooseneck seems quite robust and can be moved by means of a rotating wheel and this function works just super great!

The endoscope comes in a fairly sturdy box with a fairly thin molded plastic shell.
The device itself is really wonderfully intuitive to use.
The swivel head is easy to operate mechanically via the handle. The LEDs are controllable in 3 brightness levels (and off). Optionally, you can also download the APP "Smart Endoscope" on smartphone and connect to the endoscope via Wlan and display on the phone . The advantage, however, is that the endoscope does not necessarily need an additional device.

A nice feature is the temperature sensor in the camera head, which already gets quite warm due to the LEDs, but of course can quickly show high temperatures.
The device makes a stable and high-quality impression and delivers impressively good images with a very wide focus range.
The LED illumination is bright and you can see everything very well and record it easily. Camera and display quality are very good
The probe is waterproof. With a range of motion of 210°, you get a comprehensive impression of the interior.
All in all, a nicely compact, self-sufficient endoscope with swivel head at a rather proud price, considering the pure USB or WLAN endoscopes.

The operation of the swivel is very simple and can be operated with one finger on the handle. Clear buy recommendation from me...

The image quality is very good. I use the part more often and, for example, cylinders are easy to endoscopy.....

I ordered it for my vehicles. It's a godsend to be able to see in places I couldn't otherwise get to. This unit is well built, sturdy. It comes with a very nice carrying case, a preloaded 32GB SD card, a USB charging cable to charge the 3000mAh battery that lasts quite a while. I used it for over an hour without the percentage even dropping head on it, controlled on the device by up and down, very helpful to look around the area you are in. It has a length of 5 feet on the camera cable which is semi-rigid so you can position it as you need it , it is waterproof IP67 which means it is perfect if you need to check the plumbing in the house or otherwise.

Another great feature is that it supports audio, which is also amazing because as a mechanic I sometimes need to hear what a certain noise is doing. It supports image capture as well as 720p or 1080p video. You can stream from the device to another device with the built-in wifi for easier viewing, but this is not necessary as the built-in screen is phenomenal for viewing. In summary, if you need to take a look at a hard to reach area and see what happens, I highly recommend picking up this professional tool. K&F Concept has done a great job of building a solid unit.

I've included a couple of videos for picture quality and video quality of some random areas (one is my shed outside, in a soda can, a picture of the unit itself taken by myself,

Price-performance for this camera just great. As a plumber, you can, for example, look in front walls, under bathtubs and showers for leaks. In the automotive sector behind door panels, narrow places in the engine compartment or even cylinders, pistons and valves in the engine look. Have this camera now 1 month and thereby any amount of repairs much easier done. Have previously worked with an endoscope camera without moving tip, but with this camera it goes worlds better. I can only recommend to any screwdriver. Processing is valuable, easy to handle, almost self-explanatory, practice a little and off you go.

The device is super. Could take really good photos in the engine. The swivel function works very well.

I have used many borescopes over the years for home construction and auto repair, and this is by far the best I have ever used. This provides a very high quality display with HD quality images and video. With no instructions or information, this worked right out of the box, was simple and easy to use, and started seeing through the camera on the built-in display in seconds. After further review, I was able to connect it to my iPad with no problems and there was no lag between the screen display and the iPad. I took pictures and videos, saved them to the device quickly and easily, and then could easily transfer them to my computer for storage or review. I also love how once you have the scope where you want to fish it, you can just use the knob with your thumb to adjust the tip to look left/right or up/down (depending on orientation). This avoids the difficulty of pushing/pulling and bending it when you are so close to what you need to see. This device is also well packaged and protected in its case and I have no doubt that this will be enough for me to pass it on to my children as well.

I had to check the ground wires and ground points on my second car, because I have done a few expensive repairs so far without any results. Not all are accessible from the outside so I was looking for a cam. I have uploaded a photo of the scope of delivery.
This Ralcam has a control possibility over a screw at the handle with which one can move the point of the camera right and left. The camera is equipped with LEDs and thus also in dark corners well usable. The cable is about 1 meter long. The battery is 6000mA large and thus well suited for long operation. An 8GB SD card was also included.

Overall, I am very satisfied and excited.

Not to forget the high quality bag to store the good piece.

I bought it for automotive use but soon found it useful at home. Great price for this quality product

The K&F Concept endoscope camera comes with a sturdy storage case.
A manual and a USB cable for charging are also included.

The workmanship is impeccable and makes a very high-quality impression.

The lens head can be rotated, so you can also look in niches and spaces on all sides. The strong LED lighting allows a good image even in the darkest areas.
Everything is displayed sharply on the TFT display. You can also optionally connect to the smartphone app to save and view videos and pictures directly there.
The app is intuitively easy to use.
The device itself is operated via the 6 buttons on the display as well as two buttons next to the rotary wheel for the moving tip.
The display can be folded, so that you have a better picture outside with possible sun.
The display also shows the temperature. However, this increases by using the light function additionally.

I am very satisfied with the endoscope and can give full 5 stars for convincing quality and a good picture.
