4.0 out of 5 stars
Easy set up and does what it says on the box., 5 April 2012
It does exactly what is expected of it. Plug the two units into 2 mains sockets and they are linked. Press the security button within 2 minutes of each other and they are secure.
Speed nowhere near the maximum, but it's an old house with long and old wiring runs. For anyone in a modern and relatively small house this should work very well.
