I was looking for a flat USB hub for my USB devices Park, which has an active power, because the USB ports were no longer sufficient to my notebook. Although my notebook only supports USB2.0, I opted for a USB3.0 hub to invest in the future, after all, my laptop almost five years under his belt and the next notebook certainly has USB3.0. So I can not say much for the speed. The stroke is inconspicuously under the monitor and accepts without complaint to USB2.0 / 3.0 devices such as a mouse, keyboard, headset, joystick, etc.. Even loading IPod & Smartphone worked perfectly. From other USB3.0 hubs I've read that this WLAN to interfere in the 2.4 GHz range. I have no problems noted herein to this model. Processing I find very good, the material is dibasic, and the USB ports have a tight fit. Only the power supply could have a longer connection string, but that is whining at a high level.
