It works brilliantly - I have hardly cleaned a sensor since Nikon
introduced this in their bodies. Before that I used to clean sensors all
the time with this gizmo called SensorKlear - which is I think the easiest
way to do it. Remember that in most bodies all that you are cleaning is the
anti-aliasing filter, not the sensor, which is relatively inexpensively
replaced even in the unlikely circumstance that something should go wrong:

This is how you do it:

I still have these on hand for emergencies in the field...
