I bought the endoscope to look for beams in an old house with suspended ceilings. It mastered this task excellently. I was able to locate a beam and then made a hole in the ceiling, in which I could clearly see the underside of the beam using an endoscope. I also examined pipes, as you can see in my photos and in the video. The image quality and brightness of the front LEDs are pretty good. In my opinion, the field of view could be a little larger, i.e. show more on the sides. But it's enough for my needs. The associated app was quick to find and install. Photos and videos can be taken directly in the app and are saved in 2 folders on the cell phone. These basic functions of the app are in English or described with symbols. The endoscope sets up a WiFi network to which you have to connect your smartphone in order to then see the live image in the app. This works quickly and stably. The workmanship of the device and the accessories is very good and it comes with multilingual instructions, including in German. In the packaging you will also find a practical magnetic head for the camera with a deflecting mirror, for example to retrieve a lost screw or something similar. The camera also works underwater and the cable is bendable but stays in the desired shape. (Semi-flexible). All in all, I am very satisfied with the endoscope and the application is simple and effective. with which you have to connect your smartphone in order to then see the live image in the app. This works quickly and stably.
