I am choosing countertops for my new kitchen and fell in love with Premium Plus White from MSI. However, when I called my supplier/fabricator he (very nicely and honesty) told me that he has had some complaints about this particular stone (staining and discoloring). Has anyone had experience with this stone? I'm trying to figure out if it was just one or two people who did not know how to properly care for the counter or whether it really is a widespread issue.
