Ordered the Blackland Vector during the recent restock. Saw the Schick Proline P-30 recommended everywhere, and decided to order a cartridge. Have tried about 10 of the blades from the cartridge, and none of them fit the posts, it seems the Vector posts are just a bit too far apart. I previously had a Vector that I lost, and the blades fit perfectly. Is there a quality control issue with the most recent set of Vectors? Has anyone else had this problem?
