I bought both version mole removal pen, or freckle pen.
The bigger version is wireless, which has total 9 power setting.
Pro: wireless, 9 power setting. Con: heavier
The smaller version is wired, it is super light and easy to maneuver. But it has only three power setting.
Pro: light, easy to maneuver. Con: Wired and 3 power setting.
I tried both on my arm first, then my face. They both worked very well.
I am keeping both. Great product, save you thousands dollar to visit facial stores.
I love it
I purchased this Mini Freckle Pen to remove some small spots on my arms. What I like about this product is that it is an inexpensive way to remove spots, moles or skin tags. I also like that the Pen has different power modes from mild, middle and high. However, I must admit that the instructions were hard to understand. I tried removal on a few very small spots using the mild power and it did remove the spots. I will be going on to the larger ones as I get more courage. I did not like the burning smell but it works I would suggest using some numbing cream. In addition, I used alcohol on the spots as well as on the needles.
