For some time I already use these 4-Port USB Hub from Logitech, because there is a lack of my PC to USB ports. In addition to my keyboard and my printer, I also have connected an external hard drive via the USB port. Thus, the hard drive can bring their best performance, is supplied to the hub port even a power supply. This is useful mainly for external hard drives and printers, the rest of my PC runs well without the additional connection of a power supply. The mitgeliferte case is rather of average quality. However, I use it not great.
Overall, you can be fully satisfied with the price / performance ratio. It gets you a flawless, visually sophisticated USB hub, which is his money worth - 5 stars.
