Effective, but device doesn't seem to last long
I noticed a difference in my face, it was more lifted.  After using it for about four months, it stopped heating enough to turn on the green light (indicator for when the skin was heated enough).  The first customer service rep kept saying I must be using it wrong (though I was doing the same thing I had done for month).  A different rep agreed to an exchange because it was still on warranty so I got another one.  It doesn't heat well--the green light seldom goes on, it doesn't work as well as the first one had.  Just bad luck?
