IMO, never buy smelly chips or you will regret it. If it bugs you once you have it will continue to bug you. It really doesn't matter if other notice the smell or not but you will.
I agree with guinness, I try to stay away from China as much as I can. He just didn't want to be bunt about.
Oh BTW, I like the smell of KEM but other players don't. I still play with them. Not like all my players will notice it and pick them up and smell them.
Good luck....
