The device does what it is supposed to and with absolutely sufficient quality. The ability to create images and videos is a nice feature that allows you to share the results here. The gooseneck looks quite robust and can be moved using a rotary wheel and this function works just 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 can be easily operated mechanically via the handle. The LEDs can be controlled in 3 brightness levels (and off). Optionally, you can also load the APP "Smart Endoscope" on your smartphone and connect to the endoscope via WiFi and display it on your cell phone. The advantage, however, is that the endoscope does not necessarily require an additional device. A nice feature is the temperature sensor in the camera head, which gets quite warm due to the LEDs, but can of course quickly indicate high temperatures. The device makes a stable and valuable 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 an articulation of 210° you get a comprehensive impression of the interior. All in all, a beautifully compact, self-sufficient endoscope with a swivel head at a fairly high price when you look at the pure USB or WLAN endoscopes. Operating the pan is very simple and can be operated with one finger on the handle. Clear buy recommendation from me...
