ST-VB134 places a round head beside a short curved holding body, rather than at the end of a long wand. Its drawing marks 100.2 mm overall height and 87.2 mm across the side-view assembly; a separate 48.1 mm arrow spans the round head. The gallery also shows the power-marked control and two magnetic charging contacts on one body face. These details make head clearance, access to the control and the charging position the useful points to assess on a sample.
Evaluate the complete handheld assembly.
The published numbers describe ST-VB134, but several test conditions remain absent. They should remain source references while the sample and instruction version are agreed.
| Parameter | Published specification | What to confirm |
|---|---|---|
| External size | 100.2 mm height; 87.2 mm side span; 48.1 mm illustrated head span [1] [2] | The drawing labels the whole-assembly height and side span. The 48.1 mm arrow crosses the illustrated round head, not the grip. It does not establish a usable handle length or insertion depth. |
| Mass | Not supplied [1] | The weight cell contains a slash, not a numeric mass. Do not turn lightweight promotional wording into a measured value. |
| Drive and selections | 130 motor; three speeds plus seven frequencies [1] | No output under a defined head load or exact state timing is supplied. |
| Battery and duration | 400 mAh; 90 min charge; 60 min operation [1] | Supply rating, selected state and endpoint are unspecified; duration cannot be assumed under every load. |
| Exterior materials | ABS + silicone; electroplated detailing described [1] | The reviewed text does not identify silicone grade, plating system or their cleaning compatibility. |
| Sound | Less than 60 dB [1] | Distance and operating conditions are not stated. Do not compare directly with a measurement that specifies 30 cm or another distance. |
Keep head span separate from the curved holding body.
The supplier’s dimension drawing corresponds to the pictured ST-VB134 assembly. The 48.1 mm arrow spans the illustrated head. No separate grip-width, head-deflection or tolerance values are given. [2]

Check access to the control while holding the curved body
The multi-view gallery shows the power mark on the holding-body face, with the two charging contacts nearer its lower end. Evaluate whether the chosen grip leaves that control accessible and keeps the projecting head clear. The dimension drawing establishes the envelope, but not the contact force, grip width or comfort for every hand. [2] [3]
Treat head flexibility as an unresolved characteristic
The model description calls the silicone head flexible. Neither the drawing nor the seven exterior photographs give a permitted bend angle, load or repeated-deflection result. Obtain the actual head-movement instruction if flexibility is part of the brief; a curved body is not evidence of an adjustable joint. [1]
The control and charging contacts share one face.
This gallery view locates the control mark and two exposed charging contacts. It does not document the long-press sequence, indicator states, lead polarity or approved supply values. [3]
View the original source illustration ↗Resolve the bath wording before writing the manual.
QQIP has not performed an ingress test. This gap does not prove failure; it prevents treating the marketing language as a verified cleaning specification. [1]
| Published wording or gap | What the buyer needs |
|---|---|
| Waterproof; shower or bath use advertised | A model-matched ingress basis and explicit permitted exposure, rather than an inferred immersion promise. |
| Magnetic contacts | The supplier's cleaning, drying and charging instructions for those contacts. |
| Silicone head and electroplated ABS detail | An exterior part map and compatible cleaning-agent instructions for the actual material and finish. |
| No IP grade in the reviewed specification table | Keep the missing grade visible; do not borrow one from another SI-TOYS model. |
Make the charging routine match the supplied lead.
Identify the mating accessory
The two visible contacts identify the charging location, not an interchangeable connector specification. Request their spacing and polarity, the approved supply values and the exact magnetic lead included with ST-VB134. Check that the approved charging position supports the curved body without pulling the lead away.
Specify the indicator sequence
Have the supplier show charge-in-progress, completed and any fault indication on the approved sample. Use that sequence in the manual rather than relying on a 90-minute figure alone.
Define the duration check
For any claimed 60-minute operation, specify the selected setting, head load, starting condition and endpoint. Record those conditions with the result; QQIP has not measured that duration.
Two limits of the published sheet.
Is ST-VB134 confirmed suitable for immersion?
The page advertises bath use but does not provide a matched IP grade or test conditions in the reviewed sheet. Obtain explicit model documentation before making an immersion claim.
Is its sound figure directly comparable with a 30 cm measurement?
Not without the missing measurement conditions. ST-VB134's reviewed figure has no stated distance; the same numeric limit can describe different test arrangements.
Sources and editorial review
QQIP Editorial reviewed the ST-VB134 model page, all seven full exterior photographs and its dimension drawing on 9 October 2026. The drawing clarifies the exterior spans and the gallery locates the control and contacts. Specification figures remain supplier statements. QQIP has not operated the controls, measured grip or sound, or tested water resistance.
