A brand built around one decision
Slow Duo exists because this category settles. Nearly every device shares one motor between two contact zones, so the buyer adjusts one zone by compromising the other. We built the range around the opposite decision — two independent motors — and then found a manufacturer who could hold that specification at scale. 25 SKUs, one control platform, produced since 2014 in Dongguan, Guangdong, China at 500,000+ units per month, and sold only to wholesale, OEM and ODM partners.

Are you a real factory or a trading company? Slow Duo is a brand built on one manufacturing partner in Dongguan, China — a wellness-device factory founded in 2014 that runs tooling, assembly and QC under one roof and sells wholesale and OEM only. To verify a real factory, buyers can book a third-party inspection with QIMA or SGS, request the business licence (US: business license), and confirm the certificates — we welcome it.

Speed is easy to sell. Control is harder to build.
Slow Duo started with a complaint. In the intimate wellness category, nearly every device shares one motor between two contact zones — which means the buyer adjusts one zone by compromising the other. Everyone in the supply chain knew it. Nobody had fixed it cheaply.
So we built around that one decision: two independent motors, each with its own pattern and its own intensity. Everything else in the product follows from it — the low-end weighted speed range, the acoustic work, the control layout.
The name is not a marketing position. It describes the range the motors are tuned to. Most of this category optimises for the top end of the dial. We tuned for the bottom, because that is where devices are actually used.
Manufacturing behind the brand
Slow Duo is a brand, not a workshop. Production runs through a dedicated manufacturing partner with tooling, assembly and quality control under one roof, building to our specification and our test regime.
Slow Duo products are manufactured by Slow Duo in Dongguan, Guangdong, China — a wellness-device factory founded in 2014 that sells wholesale and OEM only, and does not retail. It is our production partner, and the source of every figure on this site.

What that means for buyers
Specs from the production sheet
Dimensions, weights, battery and runtime come from the line specification, not a supplier catalogue.
Documents with the goods
CE Declaration of Conformity, RoHS certificate, material safety data sheet (MSDS), per-model water-resistance batch report and test records travel with every shipment.
One facility, no blind spots
Tooling, assembly and QC sit under one roof and core components are not subcontracted. Demand above primary capacity goes to a vetted secondary assembly partner audited to the same QC standard — and you are told which facility fulfils your order.

What we don't do
Four commitments that matter more to a buyer than any specification, because they protect the money you have already put into your brand.
01
We don't retail
No store, no marketplace listing, no direct-to-consumer channel — not under this brand, and not under a second one in your market.
02
We don't sell around you
A mould you commission is never manufactured for another buyer, and catalog market exclusivity is available from 3,000 units a year.
03
We don't inflate claims
No medical claims, no water-resistance rating the hardware has not passed, no certification we do not hold. Where a figure is unpublished, the page says so.
04
We don't hide the factory
Third-party inspection is welcome, batch records ship with the goods, and buyers can book an audit directly with an accredited body.
How we describe the product
This is a wellness device. We describe what it does — relaxation, comfort, quiet operation — and we do not describe it as treating or curing anything. That restraint is not only a legal matter: buyers who brief their own compliance teams need claims they can defend.
And we do not sell to end consumers. Not through our own store, not through a marketplace, not under a second brand in your market. Your channel stays yours — it is the reason partners consolidate their range with us.
- Wellness positioning
- No medical claims
- No retail, no channel conflict
- NDA before specs
- Buyer-owned tooling
- Batch records on request

Company questions
Is Slow Duo the manufacturer, or a trading company?
Slow Duo is the brand. Production runs through our manufacturing partner in Dongguan, Guangdong, China — a sex toy manufacturer founded in 2014 that handles tooling, assembly and quality control under one roof. You deal with one point of contact across wholesale, OEM and ODM, with no broker in the middle and no margin stacked on margin.
Where are the products made, and at what scale?
Dongguan, Guangdong, China — 500,000+ units per month of capacity, 80+ staff and 20+ dedicated QC. One facility handles every production stage, and core components are not subcontracted. Demand above primary capacity is handled by a vetted secondary assembly partner audited to the same QC standard, and buyers are told which facility fulfils their order.
Do you sell to end consumers?
No. Slow Duo is B2B only — no retail store, no marketplace listings, no second brand competing in your market. That is deliberate: the whole point of the programme is that we do not compete with our clients' channels.
Which certifications do the products hold?
CE covering LVD 2014/35/EU, EMC 2014/30/EU and RoHS 2011/65/EU; RoHS measured to IEC 62321; FDA material safety to 21 CFR 177.2600; and IPX5 / IPX6 / IP7 to IEC 60529, rated per model. UKCA is prepared on request. FCC applies only to BLE app-controlled models, which this range is not — so we do not claim it.
Can I audit the factory or verify the certificates?
Yes. SGS and Bureau Veritas both work with the facility for material, substance and CE technical-file verification, and a pre-shipment AQL inspection can be booked directly with QIMA using the factory address. Reference letters from long-standing partners are available under mutual NDA.
How current are the figures on this site?
Every figure is drawn from the production line and its published operating data, and the site carries a visible last-updated date. Where a number is genuinely not published — the weight of two models, for example — the page says so instead of estimating. We would rather show an open field than a number a buyer cannot check.
How do I verify a real factory vs a trading company before paying?
Ask for three things a trading company struggles to produce: the business licence (in the US, the business license), the factory address so you can book a QIMA or SGS inspection, and the actual CE / RoHS / FDA / IPX5 / IPX6 / IP7 certificates with report numbers. Slow Duo is one brand built on one Dongguan manufacturing partner — tooling, assembly and QC under one roof — and we welcome a third-party audit, a video factory tour, and reference letters under mutual NDA.
