I've been trying it on a number of images and so far it seems to do a pretty good job; marginally better on some images compared to other methods, and marginally worse on other images. Again so far, it seems to do better on images at ISO 800 or less, and struggled more to keep up on an ISO 3200 image. However, as Bart noted, on the images where it is doing a good job, it achieves the results much more quickly than fiddling with the optimization of both noise reduction and sharpening separately. (On images where noise is a particular concern, I usually use either Topaz Infocus or Nik Dfine together with Focus Magic for sharpening.) It also seems to automatically recognize which areas of an image lack much detail and applies more noise reduction there. More testing to do, but I'm thinking it may have a place in my arsenal.
