Professional quality cleaning of your CCD. Keeps you shooting when you are in the field. Keeps your camera in your hands, not at the manufacturer. Visible Dust products are great quality and perform as advertised. Recommend without reservation.
To be completely honest, this thing scares the daylight out of me. A sensor is an incredibly delicate thing; sticking a hard piece plastic with a very thin layer of cotton over it, in my mind, is highly dangerous. With the cost of these and not to forget the cost of solution, you would be much better off not risking it, just send it to the company to fix. They can oil everything up and solve any other problems for you while its there.
First time user. I found it simple to use and very effective.
