What's the benefit of electric over manual? It seems from the studies that they go deeper.A cheap electric pen is good enough. Look in the opening post, check what he used.
I've previously tried using a 1mm once a week and a 0.25mm more often and saw no results, but recently read that studies found 0.6mm to be more effective than 1mm, but then if you use manual it seems it doesn't go as deep, so maybe I need 0.75mm to get the 0.6mm depth.
