It literally took 5 minutes to get this set up and working.  I have an Xbox 360 in a separate room from my internet router and was looking at options to connect the Xbox to the internet to use Xbox live, etc.  This looked like the perfect answer.  I prefer not using wireless for the increased security/speeds and this is perfect.  This adapter encrypts the communications and is fast.  I watched ESPN on the Xbox and saw no lagging/buffering.  The only downside is that Belkin suggests you plug these adapters directly into the wall (makes sense) but it is sometimes a bit difficult to find an open wall outlet.  If you are looking to extend wired internet to someplace in your home I would highly suggest this product.
