... after several months one of the devices died. I purchased a single replacement that was easy to hook up. Since then, they have worked well for several months since.

This is GREAT! At the low end I've used for connecting MagicTv to the home network for full network connectivity and use of the iPhone Remote control app. And at the higher end I use it for video streaming TV and movies to XBMC. So much easier and cheaper than running network cable everywhere.
