I have on my computer (above) only 4 USB ports. By this printer, scanner, mouse and a hard disk are connected. If still images are to be transferred from the camera to the computer, was just "umgestöpselt". Recently we bought a headset and a webcam. "Upgrading" it said now and expand USB ports. After the lightning delivery hub was then attached immediately. Windows 7 has recognized the USB hub at once. All connected devices run smoothly. The cable has exactly for my needs the correct length (30cm). Hold the plug connected and stay safe in stroke stuck.
CONCLUSION: A USB hub with excellent price / performance ratio! Strong buy recommendation
