The device does what it is supposed to and in absolutely sufficient quality.
The function to create pictures and videos is a nice feature which allows to share the results here. The gooseneck is quite sturdy and can be moved by means of a rotary 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 your 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 purchase recommendation from me...

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 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 added a few 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,

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

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.

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 is the high-quality bag to store the good piece.

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 have used this endoscope camera both in the hard-to-reach engine compartment of my vehicle and to inspect our sewer line and I find the image quality satisfactory in view of the fairly reasonable price.
If the clog in the drain pipe can be located (and cleared) without hiring a costly plumber, it's already a worthwhile investment.
Only the recording and storage function did not work and it turned out that the memory card was defective.
The seller responded obligingly and generously replaced the purchase price with a higher-quality memory card.
The durability of the camera will have to be seen, but will hardly be used due to a lack of demand.

In any case, the neighbors were already delighted that they could fall back on my "endoscope camera service" in an emergency. :-)

Does this device meet all expectations, especially in terms of quality of workmanship and image quality! Clear purchase recommendation!

The endoscope is a super solution for the DIY sector. In the professional field you might get the replacement battery for this price. Here you get a function in the form of a useful view, for example into the engine compartment or into very crooked spaces, which no smartphone camera can match. This saves a lot of time because major dismantling work can be avoided. The picture is significantly better than expected and both photos and films can be made so that you get a good overview of the condition or function of the objects that are simply to be examined, repaired or adjusted. The lighting is excellent. With strong reflections, it is very good that the light can be dimmed. I fix the endoscope with a collet so that steady pictures can be taken.

The two cameras allow quick and easy switching between front and side views.
