Photo Gadget Review - Arctic Butterfly Visible Dust Sensor Cleaner

I sit down to review the Visible Dust Arctic Butterfly 724. This is a unit meant to help you clean your image sensor in your digital SLR. I tested it out myself on a very very dirty sensor and it really made a huge difference, the first time that its. Than it just made the whole situation worse with sensor smudge that you can see in the bottom left corner of the bottom image.
