This hub disrupts WiFi connections & degrades bluetooth connections. "This AMAZON PRIME item isn't eligible for return."

I can pretty much assure you this was plugged into a 2016 or newer Macbook Pro, it was an Apple issue.
As for the rest...
Anker is almost entirely white label Chinese parts, the difference is Anker picks from the best of those and tries to instill some semblance of quality control. As such, they are still vulnerable to Chinese suppliers making unknown changes, that said, I've have very good luck with their stuff. And it's not just me, Anker is generally rated quite well, being rated as not just one of the best bang for the buck for USB hubs, but one of the best hugs in general. Their entire product lines are hat way. Even their batteries are pretty darn good.
Regarding the returns and reviews..
Amazon users are less tech savvy than even Newegg users and Newegg users are f'ing morons half the time, there is also competition and LOADS of (well documented) sabotage and fake reviews on Amazon. Seriously, don't take Amazon reviews with a grain of salt, take them with the entire salt shaker because they're bad. I'm not saying those reviews are fake or wrong, things happen and you would be amazed at what people can do to products before trying to return them.
The other issue with Amazon is Amazon. You often have no idea who is actually selling the item and if what you are buying is legitimate, you are actually more likely to get a fake item on Amazon than you are on Ebay, and that is saying something. Some of this comes from the fact that Amazon doesn't verify ANYTHING and you can't rate the seller, only the product. Because of this, fake sellers will send several legitimate products, get good reviews, then swap it out, sometimes if you read the description you will find the original listing wasn't even related. So a seller can put up a slew of cheap, legit items then redo the listing to something else entirely, or just switch to fake products, time and time again. Amazon only takes action after they get a slew of complaints, and then the seller just starts it over again under a new name. There has been a ton of good sellers run off Amazon through this sort of behavior. Seriously, it's a cess pool and Amazon is not working very hard to fix it.
Oh
If it says the item is not eligible for return it's probably coming straight from China, and is probably not an authorized reseller (could be a copy, "fell off a truck" or they were rejects). Anker has their own
shop on Amazon and they do allow returns and you can use Prime.
Don't forget the Amazon line of hubs, which are very similar. Amazon stuff is usually Chinese white label as well. Amazon basics are basically Amazon following Anker's business plan, find the good stuff and stick your name on it.
