This product was noisy and worked for a few days but then failed. I was able to return it no problem.I've replaced it with a D-Link DGS-2208 8-Port 10/100/1000 Desktop Switch and I have to say the difference is amazing. The D-Link doesn't have a fan, so it is completely silent. How can one company make a product that requires 2 fans and another company make the same thing that doesn't require any fans?Also according to other posts there are several "versions" of the same model product. You have no control over what version you get, and the fact that Cisco/Linksys has released at least 3 different versions of this same product means they are aware of the problems. Not the behavior of a quality company.
