Two years ago Pentax brought then this tool on the market. It works much like the Speck Grabber, but large-scale. With 4-6 stampings of the sensor is dabbed clean. Must be pressed after each stamp on the supplied adhesive paper to remove the dust particles the rod again.
Simple and effective, can take it everywhere (even on holiday) and takes up less space than the bellows.
Therefore, 5 points!
