Only in case of slight contamination

For coarse and loose dirt on the sensor, the product is safe suitable. But you should not expect too much here. Even if it is marketed under the name of a good camera manufacturer, it is an overpriced piece of plastic and a block-adhesive paper for moderate cleaning performance. My feeling this is only slightly above that of a bellows.

The few benefits of the product:
- The dirt is safe on paper and not in the camera.
- Large-scale, fast label of the sensor and thus not as fiddly as a bacon Graber.

Bottom line: If the price is significantly revised downwards, certainly an alternative to the bellows. But as in moderate to severe contamination of the sensor, the money is better invested in products for wet cleaning.
