I've only ever had one Anker product fail out of 50+ over the years. It was a USB A to micro B cable - the micro B connector started to bend and eventually snapped off. There was a lot of complaints on Amazon - it seems that it had affected a large number of customers. I contacted Anker, who readily acknowledged that this was a batch issue with that particular model but as they couldn't ascertain exactly which batches were affected, a replacement may well develop the same fault.

The offered me the choice of another cable (different product line) or a refund.

In that one instance where I had a problem, I think they handled it really well. The acknowledged the issue, were completely honest that a replacement with currently circulating stock could develop the same fault, and offered a solution.

With that sort of service at that price point, it's hard NOT to recommend them.
