I bought the endoscope camera for inspecting engines in my car.

I don't need to say much about packaging and shipping, especially since it has nothing to do with the product itself.

The operating instructions are in German. The description of the instructions is good and sufficient. The app itself is spartan, but sufficient. This allows you to take photos and videos, connect to the camera and set the resolution.

Transferring the image from the camera to the smartphone is wonderful. No delays or transmission errors.

The semi-rigid one is quite practical in itself, but a flexible camera would be particularly useful in the engine area. But more practical because the mirror attachment is ok and has been sufficient for my purposes so far, but the view is sometimes disturbed by reflections.

Since the camera has a battery, it also comes with a charging cable. USB to micro USB. Unfortunately, the micro-USB cable is extremely difficult to get into the camera. As a result, I used one of my cables and will not use the one that came with it.
It remains to be seen whether the battery lasts as long as the camera itself; unfortunately, in my experience, the batteries don't last that long.

Conclusion: The camera is absolutely sufficient for the price and works for its purposes.
