Hi Ivan, I have used it on my last few images and am very happy with the results It is easy to use though on my computer runs a little slow sometimes,I am low on RAM! It is available to download and use for 30 days for free,this is what I did.
I just starting using it and I'm quite impressed. It cleaned up an M1 image I have that had huge vignetting so that it really looks acceptable. I definitely plan to buy it.
