A friend of mine bought one of the discounted Benz cartridges on eBay. We removed it from the box, placed it under a microscope,and noticed that the stylus was slightly bent and is mis-aligned. My friend e-mails the HK dealer, mentions the problem, and no response for days. He had just paid $1200.00 plus shipping for the Benz, and NO response. That's where it now sits. It has been 5 days.
