My husband got this for work and he loves it. Worked really well.

Great quality, saw being used on Youtube video so decided to buy .
Used recently to source unplugged cable on car engine

the quality of the part

as for the battery, my impression is not so good - a full charge lasted only 2 to 3 hours of near continuous use. however this is good enough for my usage

Great quality. Easy to use.

Every homeowner should have an endoscope. From AC problems to plumbing issues to car repairs and everything in between, they can really come in handy. This is a really decent model for the price point. The camera image is decent (not perfect but decent). The three-camera design is very useful and makes the product more versatile. Easy to use (very intuitive) and well designed. Seems durable. Definitely would recommend.

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!

Both diameter models have the same image quality and show a clear, focused image at almost any distance.

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,
