I use this USB hub for a number of weeks for keyboard, mouse, external hard drives (with power adapter), USB flash drives etc and had no problems so far. It should be noted that this hub has no own power supply, so may the power of the connected devices not exceed 2.5 watts. It is planned, for example, several external hard drives have no external power supply to connect, this hub is not suitable. So first think, to be used for which devices the Hub! For low-power devices in this hub is top.
