However, the cleaning is quite a chore. Since the tip of SpeckGRABBERs only is 2mm narrow, you have several hundred times dab in order to clean the sensor completely. I have 3 runs (Test Photo beforehand, then dab sensor, then control Photo) needed until I was satisfied with the results. At the end there were only 2-3 tiny dots on the screen, but were only visible when the iris is less than 16. Therefore, I have refrained from further passages. With more patience and other passages, I had the points probably still caught.
The control pictures clearly showed that the dust with each pass only decreased. There were no new points to dust. The SpeckGRABBER away the dust so safe and not spread it! There are no smudges on the sensor.
Conclusion:
For quick cleaning in between the tool is less suitable. But who invest some time achieved good results and an expensive cleaning can save the merchants. I would, however, have wished that the tip of the swab would be wider in order to work more effectively.
