The ElectraStim Linx (model EM220) is the UK brand's flagship dual-output electrostimulation unit, and as of August 25, 2026 it picked up European distribution through O Products — the kind of quiet trade announcement that usually means a device is moving from enthusiast-direct into wider retail. ElectraStim has been building e-stim hardware for the specialist market for two decades; Linx is its first stimulator with full smartphone control, and the first with user-updatable firmware.

Why It Matters

E-stim has been the last major pleasure-tech category to get a proper app layer, largely because the engineering stakes are higher: a Bluetooth dropout on a vibrator is an annoyance, and on a current-delivery device it is a safety design requirement. Linx shipping with standalone-first operation and firmware updates over a desktop tool suggests ElectraStim treated that constraint seriously rather than bolting connectivity on. The wider signal is distribution — a specialist British e-stim unit landing at a mainstream European wholesaler indicates the category is graduating from fetish-adjacent niche toward the connected-device mainstream that Lovense and We-Vibe built.

What makes it interesting. Two independent output channels with 99 intensity levels each, and 23 built-in patterns — 11 wave patterns that rise and fall in sync between channels, 12 pulse patterns with distinct on/off rhythms. Crucially, all of that works standalone: the box is fully usable without ever opening an app, which matters in a category where a dead phone battery mid-session is a real design consideration. Standalone mode also unlocks frequency customization. Connect over Bluetooth to the free ElectraStim Linx app and you get nine additional play modes — Flick, Tilt, Stereo Stim among them — plus a remote-control feature that lets a partner anywhere in the world drive the unit. Battery is quoted at up to 6 hours per charge over USB-C.

The standout feature is Playlists, which ElectraStim says is a first for its stimulators. Rather than cycling preset patterns, you build sequences out of "Snippets," customizing frequency, pulse width, and rise/fall timing per segment, with different patterns assignable to each output channel. ElectraStim says a playlist can run up to an hour. For a category where most devices ship a fixed menu of sensations, programmable sequencing is a genuine capability jump rather than a spec-sheet flourish.

What the consensus is. Honest caveat: Linx is new enough that there is no meaningful body of independent long-form review coverage yet — the current visibility is ElectraStim's own product documentation and trade press (Erotic Trade Only's August 25 distribution note). Treat the feature claims as manufacturer-stated until reviewers get hands on it. What ElectraStim does have is a long track record in this specific niche and a reputation among e-stim users for building serious, well-documented kit rather than novelty units, which is worth something in a category where the cheap end of the market is genuinely unpleasant.

Price and where to buy. £399.00 direct from ElectraStim, with free UK shipping over £99; ElectraStim notes international import fees may apply and are not included at checkout. European trade availability via O Products (oproducts.eu) as of August 2026. That price is squarely at the premium end — this is not an entry-level purchase.

Materials and safety. The Linx is a control unit, not an insertable, so the body-safety question moves to the electrodes and accessories you pair with it. That is the important thing to understand about e-stim generally: this is the one toy category where "just buy the cheapest one" is genuinely a bad idea. Reputable brands build in current limiting and use bi-phasic pulses specifically to avoid the DC offset that can cause skin burns. Standard e-stim safety rules apply regardless of hardware quality — nothing above the waist, never across the chest, and absolutely not with a pacemaker or implanted electronic medical device.

Bottom line. For experienced e-stim users who have outgrown a single-channel unit and want programmable, partner-controllable sessions, the Linx is the most feature-complete thing ElectraStim has built. For everyone else, £399 is a lot of money to spend discovering whether you like electricity — start with a cheaper reputable single-channel unit first, and upgrade if the answer is yes.
