The sensor of my Canon 30D was filthy after more than four years. It was no longer possible to make usable photos without editing. Some shops told me that it was too dangerous for them to clean the sensor and the more than 100 euros, which requires sending in the Canon, I did not want to necessarily spend. I sent by Google search attention to the VisibleDust- sticks and they have the same ordered from Amazon. Add to that the cleaning fluid Sensor Clean. In just 10 seconds my sensor was again like the first day. One can really not go wrong, especially since the sensor is additionally protected by a glass plate. I can recommend the VisibleDust-Swab fully !!!
