The endoscope camera from K&F Concept really surprised me in a positive way. As a hobbyist, I was looking for a practical tool to examine hard-to-reach areas more closely. And this endoscope has my compatibility with my iPhone was an important aspect for me and I am glad that this endoscope is designed specifically for iOS devices. Setup was incredibly easy - all I had to do was download the app and connect the endoscope to my iPhone. Within a few minutes I was ready to use, almost plug and play. The 5 meter long semi-rigid cable proved to be extremely practical. It's long enough to get into tight and twisty areas, and the semi-rigid material allows the cable to be bent into different shapes to achieve your desired viewing angle. I was impressed by the flexibility and stability of the cable. The image quality is also very good. The camera has a diameter of just 7.9 mm, which makes it possible to navigate even in the tightest of spaces. The 8 LED lights provide sufficient illumination so that I was able to capture clear and easily visible images and videos. The IP68 waterproof rating was an added bonus and even allowed me to perform inspections in humid environments. The included app offers a variety of features including adjusting brightness and contrast, taking photos and videos, and live streaming the image to my iPhone. The operation is intuitive and user-friendly.
