Plug your computer into the master socket and the other 7 sockets will power up when you turn your computer on and power down when the computer is off. Includes surge protection.
I saw on this on sale as a discontinued line at Tesco Whaley Bridge marked down from £19.97, previously it was £21.99. I don't know if this is available in other stores. Not available online. Interestingly the shelf label said it was not available until 24/04/2008 but I bought one today. More details herehttp://www.oneclickpower.com/acatalog/
