This thing is absolutely amazing! I have a bad habit of going overboard with everything I do and so when I got this little machine I did the same thing. I went overboard. But because I did so, the results came so fast. I have never been like other users where I saw instantaneous results but using it for about 1- 1 1/2 hours at night while I watch TV. I began seeing a more pronounce jaw line and more tightened jowls. At about the 2 week mark of using the same way, daily, my forehead lines and 11's were greatly reduced and one small forehead line has completely disappeared. And after 1 month of using my jowls were almost completely gone and my face is completely sculpted. I don't know by how many years, but I do know I look younger than I did a month ago. You don't have to use the machine as long or as often as I do to see results but of you want them quicker, I haven't had any weird side effects or anything so I would suggest it. But I'm not a doctor or a professional of any sort so please heed my advice. And it's better than the Nuface, I think, because it has two pieces so you can do more areas of your face at one time. It works without doing the recommended pinches and holds. It works well even just to each piece along that each side of your face along the areas you want contoured. So you can do both sides at once. With the Nuface, which I also have, you can only do one spot at a time, taking twice as long to see the results.
