As with almost any hub this equipment was easily installed and used until about 15 days into use when it just quit...I don't expect simple hubs to just quit, so I had thrown the receipt and packing materials out. I have since purchased a 4 port belkin and a 4 port CyberPower hub and they are both working flawlessly. I opted for the two hubs because I wanted the reliability of the Belkin after the experience with the I/O gear garbage, but knew I needed something other than the Belkin to charge my iphone from the hub.
