Have owned this product for approximately one year and I am pleased with it but had I not done my research before purchasing I might feel differently. This product does work but the results are temporary (maximum 72 hours). I use it mostly in preparation for special occasions, although I do use it sometimes "just for fun" while watching TV or relaxing. The biggest draw back is that the 9 volt battery doesn't last long and because there is no way to monitor the power left in the battery, I find myself replacing them quite often to be sure I'm not wasting my time. I write the date on the battery with a sharpie but that doesn't help with regard to the power left in the battery. The newer model, Trinity, is rechargeable, thus solving the problem but is considerably more expensive. The biggest difference I can tell after using is how well my foundation goes on and the contours of my face are definitely more pronounced.
