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...
