It does what it is supposed to do. I have tested it with various images and videos with a large close-up of faces, photos taken from a distance, crowded places, faces seen in profile, and turned away from the camera. Light and dark photos - all anonymized very well. The pricing plans are neat - you can buy it for one day only and process all media you have if you do not plan to gather more :) The UI is simple and intuitive, you always know what you should do. A few-step wizard leads you and prompts recommended choices. Of course, you can choose where to save anonymized media, and lets you set a suffix for newly created files.

That's most intuitive software I used and everyone can achieve good results, no matter if has technical background or not.

I've just tested Gallio PRO to anonymize over 250 photos from a few different events with different lighting conditions, and... Gallio handled it very well! Every face was anonymized correctly in each photo. I also like interface and user friendly environment.
