Bests & Worsts Reviews from Amazon

This worked wonders on my briefcase, so I decided to treat my leather couch with it. BIG mistake. It absorbed so unevenly that it ruined my couch. The areas that people touch when they sit (back, arms) absorbed copious amounts and turned almost black. The surfaces that people don't touch (sides) absorbed almost none and didn't change color at all. Now I have an ugly, expensive two-tone couch. There's no way to test this beforehand because any inconspicuous test spot will by definition be a part of the couch that receives little wear, so you can't see if it will absorb differentially. Be VERY careful if you decide to put this on a leather couch.
