previously had an endoscope camera that came with a display. However, the display was so bad that the quality of the lens was not really usable. Of course, things are different here with this camera. Thanks to the Lightning connection, pairing with the iPhone is quick. Then just quickly download the appropriate app and you're ready to go. You don't need an account for the app. Just plug it in and the camera starts working. Unfortunately, the cable is a little too thin to squeeze around corners. Unfortunately, the front is not rounded enough to prevent the camera from getting stuck. The camera was well suited for my area of application (straight downwards). The brightness of the light at the front can be adjusted directly on the cable. That works well too. The photos/videos are directly on the iPhone, which is a huge advantage. However, if you swap your iPhone for a smartphone with a USB-C port, you will no longer be able to use this camera. The instructions are also in German. The description is sufficient. The quality of the camera is really good. You can see everything very clearly and the photos are taken in such a way that you can still see everything even afterwards. All in all, not a professional endoscope camera, but not to be expected given the price. Certainly well suited for a quick check of slightly tangled areas.
