Dissatisfied with grinding wheels

The wheels were not in their original packaging but loose in the envelope. Use a Makita sander, are not suitable for these discs. The disc dissolves already to edit the grinding plate in the test run without a workpiece. If these disks do not buy again. Return at this dealer yes only possible if even bear the shipping costs. Then the department will only get more expensive. So would probably be better to buy at the hardware store grinding wheels.
