Its easy to give great customer service when things go as planned. Truly great customer service appears (or vanishes) when things go pear-shaped. I want to thank Bruce (CMB Integrations) for his great follow through during my recent 568 adventure. I bought a 568.2mm from eBay, and an HD621 from Bruce. Within a day, I had strange distortion: was it the 568 or the HD621? After quickly ruling out any obvious issues, Bruce very kindly shipped me another HD621! This allowed me to identify the 568 as the issue. So Bruce not only owned the issue, but owned the issue without knowing that it was his product that was at fault. That is great customer service. Without Bruce, I'd have been unable to diagnose the issue, and probably would have missed the window to return the 568. Thanks Bruce!
