That can't be true. I don't trust the reviews even a little bit. The sites that review it all reprinted the same press release under the "reviewer"s byline, and the explanations in Amazon reviews sound bogus. "Q: I unplugged the lamp and moved it to another room and it didn't work. A: If you unplug the lamp it's no longer grounded." Bitch, when's the last time you saw a grounded plug on a lamp?
