1 out of 5 eggs Bad soldering, overly tight USB connectors. 05/17/2014

This review is from: ORICO H727RK-U3-BK 7 Port USB3.0 HUB with Premium 12V/2.5A Power Adapter (Black)

Pros: It does work, but has major flaws.

Cons: Embarrassingly bad soldering. USB connectors sometimes refuse to let go of cables.

Other Thoughts: The first thing that happened was this hub refused to let go of an Apple Lightning cable. Then, one by one, the ports started to go out. The clue was when the blue LED on each port would flicker as the cable was moved. Now, I've been an electrical engineer for over 20 years and I can spot bad soldering from a mile away.

I opened this thing up, extracted my Lightning cable, and inspected the soldering. It was amazingly bad. The obvious thing is that they intentionally used about a quarter of the solder that they should have. There were no solder fillets, and many of the holes on the through-hole pins were only half filled. I re-soldered all of the pins.

Next, I tested the Lightning cable in the other ports, and of the 7 ports, 6 of them would not release the cable. I then stretched out the "fingers" that retain the cable. Now it properly lets go of the cable, although to the surprise of nobody it is a little more loose than I'd like.

I can only recommend this hub to people with the courage, talent, and patience to open it up and re-solder all of the pins. I only bothered to open it up because at this point my Lightning cable was more valuable than this thing.
