content: I had this for around 2 years, i thought it was working. I had thought it was doing its job.The wiring in my house is old, and the previous owner left surge protector outlet plugs on every outlet in the house.I plugged in this surge protector to the outlet, until 1 week ago when I removed the previous owner's surge protector outlet plug. So this surge protector was the only thing protecting my computer.Well , what do you know , because 1 week later my computer was dead. The motherboard was fried. After turning off the power to my house for work to be done, then turning it back on, my computer which cost over a thousand was completely dead.I do not recommend this product, I do not suggest anyone to buy it. It is a terrible piece of flimsy hardware, and if you look on the internet, you'll find reports of this appliance catching on fire, and stuff like that.I went to walmart , bought 2 surge protectors and am about to ship this one back. I doubt i'll get compensation.
