I got this product with my new Ugg boots- 10 years ago.  Have continued to buy it because I can use it on all things suede and all my Ugg boots.  It doesn't discolor the suede, doesn't have a truly awful chemical smell, and really works well.  The price is good and the bottle lasts for a reasonable number of items: for me it'll do 2 pairs of tall Uggs, 2 short pairs of Uggs, (the whole boot, not just the bottom)  and four or five pairs of gauntlet type suede gloves.  And I load it on...

Do make sure you let it dry the required time, I didn't once and it didn't work as well as I knew it could.
