Bests & Worsts Reviews from Amazon

This hub totally disrupts WiFi connections and degrades bluetooth connections. I purchased 2 of these for different computers (Apple Mac Minis) and both caused interference in the same way on both computers. I happen to be a Prof. of Electrical Engineering at a major university and have verified that the problem is caused entirely by the connection of these devices to any computer of this type. I am an Amazon PRIME customer and expect that Amazon will make this item (offered through PRIME) right-- we'll see, but exactly because these were offered as a PRIME product, I was persuaded to buy it thinking that the PRIME label would provide buyer protection. It was not until later that I saw that "This item isn't eligible for return." Note that in the Warranty section of the product listing on the Amazon.com site, there is no mention of this PRIME "no return" policy. Can I trust PRIME to protect me? We'll see, and I'll update here. ANKER MANAGEMENT UPDATE: Amazon got back to me in less than 24 hours with a refund! Great service from Amazon.com. Now this may be due to the fact that I am an Amazon PRIME member, and may be a good reason for PRIME membership. As to the two Anker 4-port hubs, Amazon says that there is NO need to return them. I can just toss them into the waste bin. Thank you Amazon PRIME. UPDATE No. 2: Anker has been most accommodating and has tried to make some restitution for this defective 4-port hub design, offering cables and chargers, but I don't need those, I need a working USB 3.0 hub. So they sent me their "4-Port USB 3.0 Ultra Slim Data Hub with 3.3ft USB 3.0 Extension Cable for Mac, PC, USB Flash Drives and Other Devices". I told them that I would evaluate it and hoped that moving the hub farther from the computer might solve the interference issue and that I would give a fair evaluation here. Sadly, it is the same 4-port hub, just with a cable extension, and suffers from the same problems. I tried it on two different computers and it still adversely affected bluetooth and Wifi. Unplugging the hub instantly cures the problem. Therefore my negative one-star review must stand as a warning to others regarding this product. It needs to be heavily shielded and taken off the market until that redesign is accomplished. Sorry Anker :(
