Depends if you're buying a power strip or a surge protector. Admittedly, even if you buy a true surge protector from the local Target or Walmart, I wouldn't want to depend on one to protect against a lightning strike. But they do work very well to protect against poorly regulated electricity - probably rarely come into play in a modern city, but valuable if your area doesn't have a good electrical infrastructure.Ivan Seeking said:Store bought surge protectors are next to worthless. A quality industrial device for the same electrical load may cost $500 - $1000. But, sometimes the power strips are better than nothing.
I managed to toast a surge protector while I was in Italy. I had a transformer to convert from the 220-50 to 110-60 (the little pocket plug adaptors just don't work for CD players, computers, etc). We also had some pretty unpredictable electricity. Came 'home' and all the lights looked like they had 10 Watt bulbs. Evidently, that put quite a strain on the transformer because when they fixed the electricity and full power came back, the transformer and the surge protector were both fried. The inside of a toasted surge protector is a pretty awesome sight - especially when all the appliances connected to it were unharmed.
