It's easy to use but BE SURE TO READ THE BOOK. This is not a product that you can just dive in with and figure it out as you go. You need to know how to use it before you even turn it on. For example, you have to follow the direction of your pores and there are different directions for different parts of the face. You also can't use this on a dry face. You need to be sure to use moisturizer or toner.
There are times you use the product "shovel down" and other times, "shovel up".
I noticed a more than noticeable difference in the texture of the skin on my face. It was sooo much smoother than it was before I had used the product. I haven't been using it and entire week yet but if I can use the results from my first use as an indicator of what to expect, my expectations are sky high.
