New product

I came across this product online that seems to be the miracle I have been looking for. It is a little pricey, $75 shipped - but when I add up all the different products I have purchased over the years that didn't do much of anything, if it does what it claims to do - it will be money well spent. It also says "it is the solution you have been looking for. We guarantee it. If it doesn't work, we will give you your money back." So no harm done right? Is it called dermaflage. You can google it or look at some of the videos on your tube, that's really what made me decide to give it a try was a few of those videos. Has any ever tried this before?
