I've never used a microneedling pen before, so was a little intimidated. The device itself feels solid and of high quality. I was a little overwhelmed by all the needle options and learning how to use the device. Not a knock on the product, per se, just that if you're new to microneedling, then go into it knowing you'll probably want to do some research to understand when and how to use microneedling in general -- regardless of the features of any specific device. Once I overcame that, this product was pretty straightforward to use, and I'm very happy. I was able to reduce a skin blemish that has been visible for several years. Didn't completely go away, but definitely looks less noticeable. Good product, no complaints.
