Why it matters
The controls are a genuine strength for the experienced buyer this pen is designed to serve.
What this means for you
Six speeds, depth from 0.25 to 2.5 mm and a display showing the current setting give you real control over each session. That control rewards a user who already knows how to set it, and every session still needs a fresh cartridge, so budget for both.
The deeper analysis
Dr. Pen's listings give the M8S six speed levels, needle depth adjustable from 0.25 to 2.5 mm, cordless USB-C charging and a digital display, in an aluminium-alloy body with a three-slot cartridge lock. In use, that means you choose both how deep and how fast the needles work, the display keeps your setting in view, and the lock holds the cartridge in place.
More adjustment also means more choices to make, so the advantage is greatest for a buyer who already understands the routine. For depth, start from the depth reference chart in the M8S manual and the advice of a qualified professional who knows your skin, and keep home sessions at the cosmetic end of the range.
