Review on atolla Powered USB Hub with Long Cord - USB 3.0 Hub for Data Transfer and Charging with 4 + 1 Ports, 15W Power Supply Adapter, and 3.3ft USB 3 Extension Cable by Jerimiah Augustine

5 stars for functionality. I bought this hub to use with my tablets which only have a USB port. For connecting external devices (especially DVD/CD drives) without charging the tablet during lengthy updates or backups, an active hub is almost something special. You don't want the tablet to turn off due to a dead battery during these operations. I deduct 1 star because the USB ports are quite "tight"; To remove a flash drive or other device, you need to pull hard. When I used the rounded, flat flash drive, it wasn't easy to remove, but I was able to pry it out using two spatulas with matching cleats. [Images of an old kid's tooth trick flashed through my mind: a rope and a doorknob!]
