I don't usually write reviews but I've had a very positive experience with Anker Direct. All my cables were of exceptional quality. I had a cable that stopped working and contacted Anker support. They worked with me and sent me a prepaid shipping label to send them the compromised cable. They in turn sent me a brand new cable that works great. They certainly insist on their lifetime guarantee. I will not purchase any power supply or cable from anyone other than Anker.
