It works, Not complicated, and does what is claims to do. There are probably other similar devices that are more comfortable or a bit less tricky to use but you can't beat it for the price.

Worked as advertised right out of the box if you follow the instructions. Even with my limited computer skills, there were no problems nor was it an extremely long process.

Although I got a bit bogged down in the installation of this Windows Live OneCare software, now that it is up and running, I find it to be efficient and easy-to-use. It provides the protection that I need to keep my computer safe from viruses, spyware, and other threats.  Since OneCare works automatically, it requires very little effort on my part.  Thus far, I have not yet called technical support, so I cannot comment on how helpful they would be if something were to go wrong.  Only time will tell if OneCare lives up to its billing.  So far, I am happy enough with its performance to give it a guarded recommendation.
