Conversely, I bought one Anker product 13 years ago and it was DOA. Never bought from them again and I'm constantly surprised by the glowing opinion that people have had of them in the years since.
So he's kind of on to something. But yeah, probably just got a rare dud.
On the other hand, I've only had good experiences so I tend to reach for Anker when I need a USB adapter, cable, or power bank. They're established enough that I know I have support if needed, and (IMO) their stuff is decent quality.
I pay probably 30% more over the cheapie and know I'm actually getting what it says in the label, and that they are a long-lived reputable company that generally stands by their stuff.
It's one of the few things I buy off Amazon that I actually trust.
