Has anyone used Firefly (a type of air blower) to clean sensor

Just come across this product:
http://www.nrdfirefly.com/default.aspx

The FireFly utilizes a nine-volt battery, and safely multiplies the battery’s voltage to a point where corona discharge will occur. The corona discharge field "ionizes" the air passing through the body of the FireFly, producing and delivering both positive (+) and negative (-) air ions to the outlet air stream. This assures that static charges on the surfaces of the mirror box, shutter chamber, and image sensor filter are neutralized, allowing dust and other particulate matter to be blown off by the air stream delivered at the outlet nozzle.

I have been wanting to clean my sensor of my 1D2 but am too lazy to use swab / anti-static brush.... This thing sounds impressive but I am still skeptical how effective it is.

Has anyone used it?
