The camera set comes with a German-language user manual, which definitely helps the user, even though the device is basically quite simple and intuitive to use.

The individual buttons on the control unit work flawlessly and pleasantly.

With a battery life of around four hours, one can examine a problem quite extensively.

The three lenses at the tip of the guide wire provide a razor-sharp image on the device's own screen; at least for objects at a distance of around 2 cm to about 10 cm. In this respect, the camera is intended for investigations primarily of narrow corridors and not, for example, of sewage pipes in the ground, since for these cases the camera would have to capture and display a larger visual circle. However, the set is not designed for the latter. And the area that the device is supposed to capture and examine is displayed perfectly.

The dimmable and good illumination of the center lens is also very helpful here and also supports a clean display. With the additional illumination on the screen's housing, you can also work well in dark surroundings, i.e. you can also find the entrance of a tube into which the endoscope's tube is to be inserted without further aids.
The tube itself is quite rigid, which is probably unavoidable to move it forward at all. However, successful handling here requires some patience and practice; but then you get along fine. When handling the endoscope tube, it is very helpful if a second person holds the screen or you clamp it in some way (gently), otherwise it will wobble around in a tour and you won't be able to observe anything on it.

With its 5 meters length, the camera tube certainly allows for most household examinations without reaching its limits so quickly. At the tip of the probe you can attach a (included) hook or a (also available) magnet, with which you can also fish objects out of pipes or the like while using the camera. In addition, the camera, including the hose, is actually waterproof.

All around good and has definitely earned 5 stars!
