My Raisin GSH City still looks brand new. There is no fading whatsoever. I also baby my bags, so that's probably why. I don't treat my bags with any products at all. I've used my Raisin City, but not on a daily basis (and not too often)--not because I'm afraid it'll fade or anything, but because I get lazy and don't want to switch from my everyday bag. When not in use, I store it in its dustbag away from sunlight. So nope, no issues.
