The SI-TOYS offer and the identity still to establish independently.
The official website identifies SI-TOYS as the trading name of Dongguan Duo Ai Health Tech Co., Ltd. and publishes a Chang'an, Dongguan factory address. It describes OEM/ODM design and manufacture, including industrial design, molds, customized functions and assembly. QQIP has not matched that English company name to an authoritative registration or organizer listing during this review; the legal identity here remains explicitly website-published. [1]
The current catalog combines conventional vibration with air-pulse, wearable and other moving-device formats. Three examples on QQIP provide a narrower technical comparison: the ST-VB134 handheld massager, ST-VB118 curved G-spot vibrator and ST-VB139 potted-plant-shaped air-pulse device. They share ABS and silicone material descriptions and magnetic USB charging, but not the same battery or motor. [2] [3] [4]
The website shows factory-building and assembly-line images and a twelve-stage ODM sequence. These support a description of the supplier's stated service, not an independent factory audit. For a commissioned device, confirm the actual contracting entity and production site before settling tool ownership and the manufacturing agreement. [1]

Handheld vibration, a curved shaft or air-pulse?
The battery capacities below are catalog values in mAh, not a ranking of vibration strength or real-world runtime. Each model needs its own operating-mode and charging review. The supplier also uses 'three speeds plus seven frequencies' as a control description; do not interpret that wording as a measured vibration frequency in hertz.
| Model | Published configuration | Sample review focus |
|---|---|---|
| ST-VB134 handheld massager | ABS + silicone; 130 motor; 400 mAh battery; magnetic USB charging; 90-minute charge and 60-minute working time; 100.2 × 87.2 × 48.1 mm. [2] | Inspect the handheld grip, flexible head and plated ABS finish. Agree on the operating mode used for the stated runtime and the supplied cable specification. |
| ST-VB118 G-spot vibrator | ABS + silicone; N20 motor; 250 mAh battery; magnetic USB charging; 60-minute charge and 60-minute discharge time; 179 × 43 × 32 mm. [3] | Check shaft flexibility and button operation. The description claims IPX7, but a report for the approved ST-VB118 revision has not been reviewed by QQIP. |
| ST-VB139 air-pulse device | ABS + silicone; 300 motor; 180 mAh battery; magnetic USB charging; 45-minute charge and working time; 77.5 × 50 × 50 mm. [4] | Inspect the air-pulse contact interface and storage base. Its description says waterproof, but the table supplies no IP code. Confirm weight: the published field is a slash. |

Twelve supplier stages, four buyer approvals.
SI-TOYS' own twelve-stage route starts with ideas and drawings, moves through industrial and structural design, silicone/ABS tooling, quality checks, electronics assembly and aging, then ends with branding, packing and shipment. The four approvals below turn that stated route into decisions a buyer can document. [1]
Approve the function before the enclosure
Decide whether the device vibrates through a head, a curved shaft or an air-pulse interface. Confirm a control sequence and a sample that demonstrate the selected function. The ST-VB134, ST-VB118 and ST-VB139 motor labels should not be substituted across different architectures.
Approve drawings and tool ownership
The supplier separates industrial design, structural design and silicone/ABS tooling. Agree which drawings, enclosure revision and tool deliverables you will receive, who owns them and how later changes are priced. Neither the homepage nor the reviewed model tables gives a tooling cost.
Approve the assembled-device test plan
The website states a four-hour aging stage and complete checks after assembly. Request the mode, load, temperature limits and recording method used for that stage. A four-hour factory test statement is not a four-hour battery-runtime claim for any ST-VB model.
Approve branding and the packed sample
SI-TOYS offers product, package and carton branding in its route. Review the final controls, care instructions, cable and retail artwork together. The unbranded device sample and the final packed version should reference the same approved configuration.
Supplier-stage descriptions come from the SI-TOYS homepage. The approval structure is QQIP buyer guidance; the page does not establish an audited QC plan or contractual delivery schedule.
A listed battery and a waterproof claim need different evidence.
The model sheets are useful for selecting an architecture, but incomplete as release evidence. All three omit a numerical weight. Each repeats a below-60 dB noise claim without a measurement setup. ST-VB118's description specifies IPX7; ST-VB134 and ST-VB139 use broader waterproof wording. These are different published claims and must stay separate. [2] [3] [4]
| Topic | Published information | Buyer document or check |
|---|---|---|
| Battery and charging | 400, 250 and 180 mAh are associated with ST-VB134, ST-VB118 and ST-VB139 respectively; all list magnetic USB charging. [2] [3] [4] | Obtain the battery-cell specification, applicable documentation and charging electrical limits for the actual production revision. |
| Ingress resistance | ST-VB118 claims IPX7 in its description. ST-VB134 and ST-VB139 do not publish an IP code in their reviewed tables. [2] [3] [4] | Ask for the model-specific ingress report and cleaning instructions. Do not assign ST-VB118's code to the other two models. |
| Noise and sample weight | The three sheets say below 60 dB and leave weight without a number. [2] [3] [4] | Define noise measurement distance and operating mode; request measured sample weights rather than filling the missing fields by estimate. |
A normal 500-piece SKU MOQ is a starting condition.
The support page gives a normal minimum of 500 pieces per SKU, then qualifies it by product category. Treat that as a general supplier starting point, not confirmed acceptance of a mixed 500-piece basket. Ask whether model, color, branding and pack variants create separate SKUs and minimums. [5]
For an unchanged ST-VB model, request a quote tied to its current electronics and enclosure revision. For a new air-pulse or vibrating design, separate development and tooling from the production-unit price. The reviewed sources do not provide model-specific tooling prices, stock quantities or a fixed production lead time. [1] [2] [3] [4]
Before approving a retail pack, obtain the missing net weight as well as packed dimensions, cable contents and master-carton data. A magnetic USB label identifies the charging arrangement, not the full electrical specification or the accessories included in your shipment. [2] [3] [4]
Resolve these ST-VB specification differences.
Does the four-hour aging stage mean four-hour runtime?
No. The homepage calls four hours an aging-test stage. The individual catalog tables give 60 minutes for ST-VB134 and ST-VB118, and 45 minutes for ST-VB139 under their respective working/discharge labels. Ask how both the factory test and the catalog runtime are measured. [1] [2] [3] [4]
Are all three selected ST-VB models IPX7?
The ST-VB118 description expressly claims IPX7. The reviewed ST-VB134 and ST-VB139 sheets do not publish that code. QQIP has not reviewed a model-specific ingress report for these devices, so one model's wording cannot be reused for the others. [2] [3] [4]
Can three models share one 500-piece minimum?
The support FAQ says normally 500 pieces per SKU, with variation by category. It does not grant a mixed-model total of 500 pieces. Confirm the quantity basis for each selected ST-VB model, color and branded configuration in the quotation. [5]
Has QQIP independently verified the SI-TOYS legal company?
The reviewed company name and factory address are published on the supplier's website. An exact authoritative registration or organizer match was not established in this review. Confirm the legal contracting identity and applicable documentation before committing to a commissioned design. [1]
A useful SI-TOYS electronics brief.
Tell SI-TOYS which functional architecture you want and which part of the existing design should change. That makes the sample request distinct from a general catalog inquiry.
- ST-VB134, ST-VB118 or ST-VB139; distinguish vibration from air-pulse in the requested function.
- Required controls and runtime test mode, battery documentation and charging limits.
- Enclosure, silicone color and branding changes; drawing and tooling deliverables if the shape changes.
- Quantity per SKU, color and pack version; ask the supplier to confirm applicable minimums.
- Model-specific ingress and care evidence, measured weight and packed dimensions.
- Destination market, final artwork, sample approvals and a quoted production schedule.
Model sheets, support terms and identity limits.
QQIP Editorial reread the SI-TOYS homepage, all three named ST-VB model pages and the expanded support MOQ answer on 7 October 2026. An independent authority search did not establish an exact company match; unrelated same-name results were excluded. Specifications, process and commercial terms remain attributed to the supplier. No independent audit, product measurement, certification or client relationship is claimed.
