Over the years I have not found a single leather conditioner that did not seem overly harsh, oily, and full of chemicals. Often darkening the leather beyond recognition.
Other name brand conditioners seemed to have no richness at all and did not even effect the leather. These are the types that are sold at the big brand stores. They remove all liability of discoloration by having the conditioner do nothing.
