Would recommend this USB 4 port extender. I wanted USB v3.0 support more as a future proof but also as my Wifes iMac is USB 3.0. My own laptop has been replaced by my employer, smaller and only has x1 USB port whereas my last had x3. While working and traveling having smartphones, Bluetooth headsets charging, 3G mobile internet dongles etc, there are just not enough ports in the laptop. This works great and is put together very well.
