Stanley bench grinder replacement stones not available from stanley

Stanley tools a global name . SA stanley bench grinder is sold to the unsuspecting public without any support. The grinding wheels 150mm are a natural wearing item, but NOT stocked by stanley tools SA. Therefore once they wear out and require replacing - you own a very expensive doorstop. I contacted Stanley head office JHB and was advised to speak to their manager who said -''we dont stock the grinding wheels - sorry'' Its simply ''buyer beware'' - they will not refund either so you have been warned.
