I bought this both as an extension lead for my computer and the myriad of devices that seem to be associated with it, and as protection against surge. It fulfils the first task admirably, with the two rotating sockets proving very useful for block type transformers. As to the second task, I will have to wait until we have another thunderstorm to find out how effective it is, but I am assuming that because Belkin are prepared to insure your equipment against getting fried and are putting their money where their mouth is, it works! Overall, it seems well made and inspires confidence.
So why 4 stars and not 5? Because it would have been much better if each of the sockets was individually switched. As it is, there is one switch that covers all sockets.
