Maybe because your opinion was shaped by their efforts. Perhaps maybe you would’ve bought from Anker instead? Perhaps they were able to charge you $30.99 instead of $10.99 after they faked the reviews.
I was recently shopping for a USB hub, and Anker and Aukey had what appeared to be the exact same offering with different branding. It made me believe that they use the same OEM, but I'm not sure whether that's actually the case since I'm not familiar with their engineering and manufacturing processes.
I have only ever heard good things about Anker but their premium price has kept me from purchasing them. I bought Aukey several times because they were considerably cheaper than Anker.
I was and still am impressed with their quality and with their support so I have continued to buy their products.
I really like their now outdated PA-U32 USB power supply, it was a great value for the money and I probably have a half dozen or more.
I think all of my USB powerbanks are Aukey and I have been happy with each.
