Pros: Either they work or they don't.

Cons: Of the 7 out of 8 I've tried I've had 4 bad one's which caused me hours of wasted troubleshooting. Cheap connectors in one of the packages and the wiring didn't stay in the plug and wires were falling out. I of course was trying to run 1070's and I thought I might have a bad card. I eventually got them all working, but after much frustration. I would never buy these again.

Overall Review: Don't get frustrated buy something that cost a little more and will work.
