One of our shooters picked up some information about this at Imaging USA. This thing completely (99.999%) eliminates sensor spots - period. It almost seems like magic. I was wary of what I had heard about this software, then I tried it. It does it's job without losing image clarity, without going through the images manually, without using Lightroom or anything like it. It even cleans spots that overlap the edges of an image onto the background without screwing with the line between them. It just works. It offers the automatic cleaning functionality for at least 20 images and individual image cleaning when you have less than 20.
It has already saved us hours of time between our 2 locations going through several hundred images and we just bought it yesterday.
