I purchased my NuFACE Trinity last fall. I have to say there is a short learning curve with this product or there was for me. It took me a few times to learn how to use it properly and for the first week or so, it took me about twenty minutes to do my whole face. Now I can do my face in about five to ten minutes. It has five different levels of strength. I am now up to the strongest level, and I can really feel it at times. I would suggest starting at a lower strength until you get use to it. It comes with Gel Primer which you must have to make it glide smoothly. The tube will last a long time if you use small amounts, and it only takes a small amount for each section of your face. Only use this device on a clean face. I am really seeing a noticeable different in the tone of my face; however, the secret to this product is consistency. I have had to use it everyday for about three months to see a real difference in the firmness of my complexion. It is really working though. I would highly recommend this product if you are willing to commit to using it on a regular basis.
