Great results, better than expected
Brand new nubuck couch took a full bag of microwave popcorn grease in the first couple of days.  Huge deep stain on couch.  I did some research on products, decided to try this one with honestly low expectations.  The stain looked like the kind that are permanent.  Followed directions and patiently kept doing a quick treatment every few days.  I would say after about 4 treatments I could see dramatic improvement. I would say 6 treatments, each lasting about 60 seconds with drying time in between was all that was needed to make grease stain disappear. I am blown away. Highly recommend if you are patient and can follow directions.
