leather isnt like cladding, cladding is going to take that hard to find product that really is inadvertantly doing a good job because there isnt a "cladding conditioner", theyre all made to work on everything, theyre all kindof a jack of all trades product not specifically for cladding. but leather, everyone makes a good leather softner and conditioner, try them all and youll find that most of them do the same job, ive used a lot of them and most were just like each other. saddle soap is great, holds up for damn near eternity. In my own opinion, theres no one product thats the only conditioner, leather is easy to care for, and many products do it well. So, undo the tops of each one, and select one that smells nice, because whatever you saturate into the leather....youll have to deal with smelling for a long time. And since most work alike...that would be my next most important concern.
just like the guy was telling you about hyde food. other stuff will work as well but not smell like horse piss.
If it were me.... id spin the cap off a meguires or zymol leather care kit and smell em, use the one that smells best. theyre both super at making great car care kits. Their name says enough.
