The product perfectly fulfilled its task, despite a little "cheap" look. It has two USB ports (one for data and power and another dedicated solely to food), which is a plus when feeding a single USB port is too low (even though I have few had the opportunity to test. Two small LEDs indicate that the drive is connected (red LED) and whether data are transferred (LED blue), which is rather nice. A product so I recommend if you want to connect for example an internal USB drive with no need to carry a box. Be careful though, the 3.5 "disks need more energy and will not work with this accessory, which should be reserved for 2.5" drives.
