The only issue I have with the Mintcell risers to date is that once in a while the USB cable itself is iffy - but they're standard cables and cheap/easy to replace when that happens.
How does one determine the USB cable is iffy? I've had a few problems with Mintcell risers where the rig would freeze/lose GPU connection while mining - I just assumed they were beyond repair and replaced them. What are the signs of bad USB cables?
Also, check this out... Mintcell risers I got last week:
