Device with low quality - Not highly recommended!

I bought this unit to connect 3 USB printers and a Wi-Fi stick with the laptop, which has not enough own USB connectors. The device is small, found everywhere on the desktop space and is first recognized when inserted. Even a printer running smoothly, is to say, it will be recognized correctly. Another printer is detected only sporadically occur when sending print jobs often during printing error messages, so I had to remove the printer again. Not much better functioning of the port that I use for the WLAN stick: Again, there are frequent error messages ("Stick not plugged in"), although the stick is plugged in correctly! Result: The wireless / internet connection often breaks off and must be started cumbersome new ... Conclusion: The device is to use for continuous operation NOT! The relatively low price (10.85 EUR) should not lead to buy. I'll look around in any case to another device.
