My Fellowes Surge protector was taken right of the box brand new from the Amazon packaging and plugged into an electical outlet. POP. Lights and everything electronic in the room stops. Hmmm. Reset the breaker. Plug it into a different outlet... POP! Hmm. Reset. Plug this item into an outlet other side of the house... POP!So to double check everything, plug this device into an outlet at a friends home... same thing.. POP!Obviously my unit had some kind of internal short circuit right out of the box and was completely unusable.A new one might have worked great, but in my situation I sent it back to Amazon and will spend a couple dollars more and buy the 12 outlet 2,400 joule surge protector from Belkin instead.Thank God for great customer service from Amazon.com!
