I LOVE micro needling but I don't like the small talk and the setting of getting it done professionally. This is a great alternative for me. I can mix my own serums to inject and I get so much more out of the treatments since I can relax and actually enjoy the treatment. The tanks are a little small so you have to stop halfway thru to refill but to me that's better than paying $100 plus each time I go to get it done. Not to mention the small talk, the awkward pauses, I'm just not a people person. This pen is GREAT and so easy to use.
