E-Fun Trainer

The E-Fun Trainer uses a combination of textured friction and variable vibration patterns to gradually desensitize the most sensitive areas. Through regular training sessions, your body adapts to stimulation, helping you maintain control during intimate moments.

Most users report noticeable improvements within 2-4 weeks of consistent use (3-4 sessions per week). However, results vary based on individual sensitivity levels and training consistency. For optimal results, we recommend a minimum 30-day training program.

Yes, the E-Fun Trainer is designed with discretion in mind. The product itself resembles a tech gadget or collectible rather than a traditional toy. All packages ship in plain, unmarked boxes with no indication of the contents. The shipping label lists only "JS Health Products" as the sender.

Thanks to its IPX7 waterproof rating, cleaning is simple. Rinse thoroughly with warm water and mild soap after each use. Allow to air dry completely before storing. Only use water-based lubricants as silicone-based products can damage the silicone sleeve.

The E-Fun Trainer operates at less than 50dB (quieter than a normal conversation), making it very discreet. At lower settings, it's barely audible from the next room, even in quiet environments.

Yes! With its IPX7 waterproof rating, the E-Fun Trainer is fully submersible and safe for shower use. Many users find incorporating it into their shower routine adds convenience and privacy to their training sessions.

The 10 vibration modes progress from gentle to intense, designed to gradually build tolerance. Start with the lower intensity modes and advance to stronger ones as your sensitivity decreases. The one-touch button cycles through all modes - simply press to switch to the next intensity level.

Unlike standard strokers focused solely on pleasure, the E-Fun Trainer is specifically engineered for performance improvement. Its precision-textured interior and progressive vibration system are designed for effective desensitization training while still providing an enjoyable experience.

The E-Fun Trainer provides 100+ minutes of continuous use on a full charge. Charging is simple with the included magnetic charging cable - just attach it to the magnetic charging port and connect to any USB power source. A complete charge takes approximately 90 minutes.

Yes, the E-Fun Trainer uses premium-grade, body-safe silicone that's phthalate-free and non-porous. The material is hypoallergenic and designed specifically for intimate use, with just the right balance of softness and firmness for effective training.

This is normal battery behavior, not a defect. Lithium batteries naturally enter sleep mode and lose charge when unused for extended periods.

To prevent this issue:

• Charge your device monthly, even when not in use

If your device won't power on:

• Charge for at least 1 hour before attempting to turn it on
• The extended charging time is necessary to wake the battery from deep sleep
• This is standard for all rechargeable devices and doesn't indicate any product failure

For persistent issues after following these steps, please contact our customer support.
