Generally my experience with Anker in the past 5 years has been solid products. Then again I don't buy their cheapest stuff and they are being compared to some truly garbage competitors. I have like 5 of their charging hubs, 3 of their batteries, and one of their car chargers and I've never had a problem with any of them.

Every time I buy non-Anker USB charging stuff I end up regretting it. Although I have had problems with their USB cables, the micro-USB ends always get loose after a year or so. But this is kind of a microUSB thing anyways.
