I purchased Belkin 6 socket surge protector to protect my office desktops from frequent power fluctuations and also to increase the no. power sockets to connect 3 pcs. I have used some local brands and they are merely glorified extension cords and did not provide any surge protection. This is a good product for those interested in surge protection. If you are using inverter you will still require surge protection particularly when there is a change over from mains to inverter power and vice versa.
