Review on 🔌 Zouhi USB Hub 3.0 Powered: 7 Port Data Hub Splitter with Power Adapter, On/Off Switches, and Long Cable for Mac Pro, MacBook Pro and More by Dezz Watson

At first I thought this case was excellent. but. after a few days, i noticed a ram was burning in the pc, and then other anomalies. Finally, the computer would not even turn on with the power button. Turns out the hub was feeding 5V BACK into the computer's USB port, keeping things going and never putting the computer to sleep. Imagine spending hundreds of dollars on a power bank just to plug a 10 cent wall wart into your USB ports. It was already mounted under the table so I unplugged it and threw it away. The lack of a simple diode could have been detrimental to this new $1,000 dice assembly. UPDATE: The seller contacted me and sent the money back. They said they would fix the backfeed issue in an updated build.
