The 20 Series is the smallest M1 and the one to start with. It takes single-conductor heads, so it runs on one channel and one cable — the simplest way into the system, and the easiest to get comfortable with. Everything you learn on it carries straight over: the accessory pads are shared across every series, so moving up later costs you a probe, not a setup.
New to the M1? Read the system overview first — how the PlaLok™ parts fit together, what each part does, and how the series differ.
Configure yours:
- Head — Cylinder: even stimulation, fuller feel, 45° base angle for strong pull response. Sphere: smaller contact patch, more focused intensity. Head Size is the head's diameter, not the shaft. (More shapes in 20 Series Heads.)
- Base — Sloped: maximum movement range. Curved: more clench, less motion. Hopper: angled for maximum movement intensity. Button: compact, minimal profile.
- Shaft — 60mm (Regular) is the one to start with. 55mm (Short) and 65mm (Tall) move the head relative to the prostate, which changes how it sits and feels.
- Accessory — None, ClitPla™, PeriPla™, PeriPla™ Deep (longer, more concave), or the Peri C. Choosing a pad includes the accessory collar that locks and powers it. None does not include a collar — order the Insulating Collar separately.
ClitPla™ is the vaginal version of the same idea: the probe goes in the vagina and the pad lines up on the clitoris the way PeriPla™ lines up on the perineum.
The Peri C is the upgrade: it is the only pad with insulated sides, so the sensation goes where the pad sits and nowhere else — the others are conductive across the whole face. It also has a raised center ridge that follows the natural seam and a slightly concave face. Rigid PLA, or TPU which flexes with you.
Cables: the head connection needs a straight 4mm end — a 90° connector doesn't clear the shaft, and the connector must be 8mm or slimmer. The PlaStim cable in 90°/straight is the go-to.
Worth knowing: under the head port is an M2×40 screw hole. Installing the screw cuts connection resistance about 30% and reinforces the neck — optional, but it's there. All parts are consumable: inspect before every use, disassemble fully to clean (warm water + dish soap), and read the Care and Safety Instructions.
