I'll be the voice of dissent here. I've heard nonstop praise for Anker online. Bought a couple keyboards and adapters from them and they all failed within a year. My wife got a mobile battery from them and that ended up dying in under a year as well. I'd be willing to write off one bad item, but I've had no good experiences and the pattern is clear to me.
It's mediocre trash. But in relative terms... the bar is so low now and the market flooded with randomly named fly-by-night operators that even mediocre trash stands out as exceptional just by existing long enough with a consistently spelled brand name to not be perceived as a fly-by-night operator.
Did you buy them off Amazon, or from a reputable reseller? I ask because Amazon mixes third party inventory together with first party inventory, so it's impossible to tell if you're getting a genuine product or a counterfeit.
>To avoid commingling, sellers have long had the option to apply a unique, seller-specific Amazon barcode — known as an FNSKU (Fulfillment Network Stock Keeping Unit) — to every product. This ensures their inventory is tracked and shipped separately.
... is that really all that was necessary all along? I can see that being a problem for, like, 10 cents worth of stuff, but a lot of the commingling complaints have been around expensive items. It's not zero cost of course, but for your average $30+ thing it doesn't seem very difficult to justify.
I feel like anker combines mediocre quality control with pretty good customer service. A lot of the praise I hear from them includes something like "it died but they replaced it for free".
FWIW, after reading a few comments below you, I discovered that their usual warranty is 18-24 months. I've got a power bank that I had assumed was out of warranty (> 1 yr) but I'm still within 18 months so back to them it will go! You might find an equally pleasant surprise.
