Works great,
4 stars due to the smell but it dissipated within a few hours.  I used this on a 20 year old leather handbag.  I applied with my hands, just rubbing it on all over.  At first I was a bit concerned about the color as the bag darkened a great deal.  I put it on then set aside for 24 hours.  My bag looks great!  It once  again is soft, supple, and only a tiny bit darker - maybe darker isn’t the right word.  The color is the same but more intense.  I only used a tiny amount as a little goes a long way.
Rating: 4 stars
