“I ordered this little hub because I needed to add two USB external drives to my Raspberr Pi 3 and it could only cope with one. I ordered the item on Thursday and it had arrived by Saturday (and that being a Xmas weekend). I pluged it to the mains, plugged it to the Raspberry and plugged the external hard drive to it. I was ready to go in a matter of minutes and no more issues with the USB drives not getting enough power to run. The bright LED doesn't bother me much since I don't sleep in the room where my Raspberry is located. Brilliant little item!”
