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 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I really like their now outdated PA-U32 USB power supply, it was a great value for the money and I probably have a half dozen or more.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.
