I love this so much better then my other Dr. Pen products. This doesn't hurt as much as the previous products and injects my serums right my skin. It's easier to use then previous Dr. Pen products. After using it once my skin looks great! Several people at work have conmented on how good my skin looks just this past week alone. I will be ordering one for my daughter for her birthday and recommended it to all my friends turning 30 or older. The only complaint I have is that the cup for the serum is a little small. I'd prefer a bigger size so I don't have to stop to refill it when doing my face. It's still a lot better then things I have used in the past.
