Four-Head Detachable Rotating Vibrator Kit

Four heads make the connector the central feature

The four-head detachable rotating vibrator kit concept pairs a deep-plum rechargeable handle with a rose-gold coupling collar and four distinct attachments: smooth curved, wave-textured, split-ear and graduated three-bead forms. The variety is useful only if every head locks predictably, runs concentrically and can be cleaned without trapping residue.

No attachment material, insertable length or motor specification is approved yet.

The head inventory needs fixed names and dimensions

Assign each attachment a model code and record overall length, usable length, maximum diameter, curve offset, texture height, split-tip spacing and connector depth. Packaging, instructions and replacement-part lists must use the same identifiers.

Reject mixed kits where visually similar heads use incompatible couplings.

A positive lock should be visible and tactile

Confirm whether the coupling uses a bayonet, threaded collar, keyed latch or another system. Measure insertion force, rotation angle, pull-off force and the clearance that remains when the head is fully seated.

A head that can be installed halfway yet still run is not acceptable.

Concentric rotation protects comfort and hardware

Measure runout at the connector and tip on every head at every rotational level. Excessive wobble can create uneven contact, overload the motor and work the attachment loose.

Stop for knocking, scraping, visible eccentricity or a coupling that migrates during operation.

Torque limits matter when a head meets resistance

Request stall-current, torque-limiting and automatic-stop behavior. Test with an instrumented fixture rather than gripping a moving head by hand, and confirm that stalled motion cannot overheat the handle or twist the coupling open.

The device must stop promptly from its physical control even under load.

The smooth curved head prioritizes broad contact

Check the radius, tip rounding, shaft transition and balance of the smooth attachment. Its curve should not hide a thin neck near the connector or place the largest diameter beyond the verified usable zone.

Begin at the lowest setting with light external contact while fit and movement are still being assessed.

The wave head needs valleys that can be reached

Measure the height and spacing of every ridge and inspect each valley for mold flash, seam steps and abrupt texture. Deep waves can collect moisture if the cleaning tool and validated care method cannot reach them.

Do not use the textured head if the surface snags a soft inspection cloth.

The split-ear head needs independent flex checks

Record ear thickness, free spacing, bend radius and compression force. Run fatigue cycles to see whether either branch leans into the other, tears at the root or contacts the rotating collar.

This attachment should be treated as an external contact head until its intended use is documented.

The graduated bead head requires careful sizing

Document each bead diameter, valley radius, total usable length and the transition into the connector. The illustrated head has no verified flared base and is not approved for anal use.

Discontinue use for pain, numbness, pinching, irritation, bleeding or unusual sensation.

Rotation and vibration must have separate controls

Map whether the motor rotates, vibrates or combines both, including direction, speed, patterns, startup level, memory and long-press shutdown. A single button must not make an unexpected jump from a gentle pattern to rapid rotation.

Record the complete sequence in the product instructions after sample validation.

Battery performance must be tested with every head

Confirm chemistry, capacity, USB-C input, charging time, low-battery behavior and run time under the lightest and highest-load attachments. A quoted runtime measured without an attachment does not represent normal operation.

Charge detached from body use on a clean, dry, nonflammable surface.

Water can enter through the detachable coupling

Request the assembled ingress report for the handle, button, charging port, head shell and connector interface. A sealed-looking head does not establish that the open coupling or motor shaft can be rinsed.

Keep every connector dry and do not immerse any part unless exact test evidence and instructions permit it.

Materials must be identified head by head

Obtain composition and restricted-substance records for every outer head, internal core, pigment, adhesive, collar, seal, handle shell and port cover. A claim for one attachment cannot be extended to the other three.

Check each production color for odor, tackiness, staining, cracks and surface change after validated cleaning.

Cleaning begins after the motor is fully stopped

Power off, wait for all movement to cease and detach the head using the specified release action. Clean each wettable attachment according to its verified method while wiping the handle and connector separately.

Dry the coupling recesses completely before assembly, charging or storage.

The supplier lead defines a sample brief

An Alibaba China listing describes a four-in-one detachable rotating vibrator at USD 12.63-14.18 with MOQ 50. Supplier identity, exact unbranded kit, attachment geometry, coupling endurance, motor map, battery, ingress protection, materials, certifications and purchasing terms remain pending.

The procurement reference supports comparison and sample inquiry only. The EUR 69.99 plan includes China-origin freight allowance, four-head dimensional inspection, coupling fatigue, runout, torque, runtime, ingress-document and cleaning validation; actual freight, duty and tax remain pending.

Frequently asked questions

Do all four heads rotate?

The motion available with each attachment must be confirmed on the exact sample.

Can a head detach while running?

It should not, but positive-lock engagement, pull-off force and endurance require testing before approval.

Is the three-bead head suitable for anal use?

No. The illustrated attachment has no verified flared base and is not approved for anal use.

Can the attachments be immersed for cleaning?

No immersion method is approved until material-specific care instructions and ingress evidence are reviewed.

Does the handle vibrate as well as rotate?

The motor functions, direction and pattern map remain unconfirmed.

Can third-party heads fit the connector?

No cross-compatibility is approved; use only attachments identified for the exact handle and production revision.
