The Hub, a very sober look, robust appearance, takes up little space, but it is the counterpart of 10 ports available. However, its power transformer is too large for this type of accessory: it takes almost as much space as the housing hub! The installation is done automatically with all versions of Windows from XP to W8 (I have Windows 8, which despite its faults, was recognized immediately). It supports USB 2.0 and 3.0 ports, but it does enjoy its speed with the 3.0 then it supports up to 5 Gbps of throughput! I tested the connection of all my devices (7) USB port: it fits perfectly in shock. I must say it has its own power supply (cumbersome it is true) that connects the power intensive devices. It may, on-efficient devices work without diet: rather than using the microscopic On / Off button, I unplug the transformer by hand, it's easier. In short, a great buy especially recommended for owners of USB 3.0 ports, which avoids losses of flow of a 2.0 hub
