The M1 Modular Probe System

The most advanced E-Stim probe in existence. That's a bold claim. We can back it up.

How it started. The M1 began with one idea: use the probe as an anchor to hold a perineum pad in place. In testing, the pad became a pivot point — the slightest pelvic floor contraction rocked the probe head against the prostate, like an Aneros massager, maybe better. And that was before the E-Stim turned on. The early prototype was a solid one-piece probe, five hours per print; every design change meant another five-hour wait. That frustration became the question that built the platform: what if every part was detachable?

The PlaLok™ system. Every M1 is four parts — head, shaft, base, collar — that lock together with quarter-turn tangs and a visual lock indicator. Assemble, twist until it clicks, pull to confirm, check the indicator. Every part is interchangeable within its series, so a new sensation costs one part, not a new probe. Parts are consumable: inspect before every use, limit lock/unlock cycles, and read the Care and Safety Instructions before your first session.

The series. The series number is the shaft diameter — pick your size, then build inside it:

The parts. Heads set the sensation profile — from even and full to focused and intense, with multi-conductor heads giving independently controllable zones. Head Size is the head's own diameter; the series number is the shaft. Shafts set length and angle. 60mm is the regular length and the one to start with; 55mm and 65mm move the head relative to the prostate. Lower angles follow the natural anatomy; higher angles add prostate pressure. Bases set the movement character. Collars are the fourth PlaLok part: the insulating collar, or swap in the accessory collar, which locks a pad in place with the same 4mm banana plug that powers it. The insulating collar is sold separately — a kit with Accessory set to None does not include one. Accessories — the PeriPla™ perineum pads and ClitPla™ clitoral pad — fit every series. ClitPla is the vaginal version of the same idea: the probe goes in the vagina and the pad lines up on the clitoris.

Why modular wins. Buying every insertable from one major manufacturer would run roughly $7,000 USD — and you'd still be missing the shapes a lathe can't make. With the M1, a new head is about $17, a new base $15, a new shaft $7.50. The ecosystem keeps growing, and your probe grows with it.

Part numbers follow one grammar: M<series><part>-<name><conductors> — so M25H-EYES3 is a 25-series Head, Eyes profile, 3 conductors. Accessories carry MA- because they fit all series. What's on the label is what's in your hand.
