I'm using this hub with my MacPro for almost a year now, on a daily basis.It is a powered hub (which is good when connecting multiple devices).5 connections in the back should be plenty for most; I use it for 3 DVD bruners, a GPS device, and a webcam.It has 2 USB connections on top which I find very practical for those devices that you unplug and unplug frequently like a USB pen drive or a digital camera.After almost a year it still work great and I can highly recommend this item.
