Review (1/5): Not really...
I can't say that it worked for curing gel nail polish, but it did work for pain relief. I gave them as gifts to only have people go and invest in gel polish to be ticked off that it didn't work. However, one of the friends that I purchased one for told me that she read that UV light worked for pain. She later called to thank me because it cured the pain in her leg. So to say that it didn't work would be completely untrue. It did work for something.
