After 7 years of using several brands of leather conditioner I've finally wised up and tried Lexol! The Lexol soaks into the leather, conditions it, and slowly seems to stretch the leather which is starting to diminish the cracks. It also makes the leather much softer to the touch. Wish I used it a lot sooner, but better late than never. I got the large bottle of conditioner and cleaner on Amazon for 25 bucks, and it will outlast me and the car. I'm doing the seats every few weeks, but eventually I should only have to do it every few months. I noticed a very small bottle of the Lexol in one of the larger stores for 6 bucks if you wish to see what a sample does. All the other conditioners I was using seemed to simply put a coating on top of the leather.
