When cleaning the sensor, a damp film that does not also dissolves arises. Strange cleaning fluid.
The included manual is only available in English and probably poorly translated from Chinese. I used the swabs how common uses Reinigungsswabs. Once in the one direction, once in the other.
In these here then a huge mess created in the sensor and is looking forward to have move the camera to the repair.
I will complain in Swabs as completely useless.
I can recommend this junk therefore no - more than the person who wants to make the sensor broken.
