Like many of you, I have only USB 3.0 on my laptop. With this hub, no problem, I can connect all I want at high speed. Very useful for transferring photos and videos from an SD card to an external hard drive. Very chic and light thanks to the brushed aluminum finish. Extremely simple to use with plug and play and hot-plug which require no installation or manipulation. Unlike other models, catches are sufficiently separated that to connect 4 devices simultaneously. In addition, it is lightweight and compact. So we took her everywhere easily.
