Model selection: Match functions according to needs:
Vibe basic model, clitoral vibration [For beginners/those with limited budget]
Liberty 6-level intensity + intelligent silent technology, medium size [For mainstream choice with balanced functions and prices]
Premium 14-level intensity + automatic mode + intelligent adjustment of suction mouth fit [For those who pursue the ultimate experience/advanced players]
Classic classic model, 6-level intensity, waterproof design [For cost-effective mid-range choice]

3. Key considerations
Intensity range:
Sensitive constitution → choose the mild model at the entry level (such as Vibe);
High stimulation resistance → choose the high-intensity level of Premium.

Fitness:
The shape of the suction mouth affects the experience (oval is universal, round is more concentrated), and Premium's technology can automatically sense fit.

Material safety:
The suction mouth is medical-grade silicone (porous and antibacterial), and the body has passed international certifications (such as CE, RoHS).

Quiet performance:
Library-level quietness (<50 dB) Ranking: Premium/Liberty > Classic > Starlet.

Waterproof design:
The entire series is waterproof (IPX7 level), suitable for bathing, and more thorough cleaning.

4. Advanced functions are optional on demand
Automatic mode (Premium exclusive): automatically changes the intensity rhythm to free your hands.

Magnetic charging: standard for high-end models to avoid corrosion of the charging port (especially for bathing).

Travel lock: Pro40/Premium is equipped to prevent accidental start.

5. Test recommendation
Beginner's guide:
Liberty (about $558-731) is fully functional and has a low fault tolerance cost.

Pursuing the ultimate experience:
Premium 2.0 (about $1580) smart mode + wide intensity, large space for exploration.

Summary: 2-step decision-making method
Budget positioning:
$558+ (Liberty/Classic) → $1580+ (Premium)

Evaluation sensitivity:
For low tolerance, choose the weak basic model; for high tolerance, choose the wide strength model.

Usage scenario:
For frequent use in water, choose the waterproof model; for privacy, choose the model with strong silent technology.

Important reminder: Start from the lowest level for the first use to allow the body to adapt; when cleaning, rinse the mouthpiece with mild soapy water and store it in a breathable cloth bag to avoid light and dust.
