Excellent if you get this one that is blue. Most of the time you will not get a USB device to work past 2-3 of these stacked together.

I ordered two of the USB 2.0 extension repeater cables. The overall quality of the cables were good, the female end of the cable was not as sturdy as I would have liked it to be but it did the job. The product description states that you can connect up to four of these cables together to get a length of 60 feet. These cables work fine if you are only using one cable. When I tried to use two cables, my XBOX 360 wireless network adapter would not connect to my wireless network. I would get a blinking green light instead of a solid green light. When I went back to just one cable the wireless adapter connected just fine. The bottom line here is, if you need more than sixteen feet of extension, this product will not work if you connect more than one cable.
