Good microneedling pen, but unless you're already well versed in the world of microneedling devices and techniques, you'll have to search for instructional videos online because Dr. Pen is pretty lacking in this regard. Other than that the product itself is great. high quality construction despite being so small and light. A full charge out of the box and I haven't had to charge it yet after 2 months. There are 6 needling speeds for your needs. Replacement needles in the box for multiple sizes. All around great package.
