Review on 🔌 Unitek USB Ethernet Adapter 7-Port Hub: Gigabit Ethernet Converter, USB 3.0 Hub, Charging Port, 36W Powered Splitter – Compatible with MacBook, iMac, Surface Pro, Laptop PC, HDD by David Crowder

This USB hub can be incredibly dangerous for your computer. Perhaps it is the reverse current back into the device that can short out various parts of your computer and cause a lot of costly damage. Backfeed can also prevent various things from resetting properly or power off completely. I think my hub is back-powered because when I unplug the hub from my computer and from the outlet it still turns on the lights on my keyboard. I unplugged it for over 48 hours and it still lights up my keyboard. He shouldn't keep the food for so long. I would like to point out that otherwise it works well - I just don't think this product is worth the potential risk of destroying an expensive computer. If this is considered normal behavior, the product description should be updated. It took me a while to figure out what it does, so unfortunately I'm right outside the return window. However, I'm willing to update my rating if the seller sends me a replacement and the replacement doesn't behave the same.
