User Guide & Operation Manual

Frequently Asked Questions

How does the dual-channel training system work?

Channel A offers high stimulation with lower training intensity for beginners. Channel B provides moderate stimulation with high training intensity for advanced endurance building.

Is this safe to use regularly?

Yes, it uses physical desensitization training with no side effects or dependency. The body-safe TPE material is designed for regular use.

How long does it take to see results?

Most users notice improvement within 2-3 weeks of regular training. The three-stage program builds endurance gradually for lasting results.

Can I use this in the shower?

The interior liner is IPX7 waterproof, so you can rinse and clean it thoroughly. However, avoid fully submerging the entire unit.

What type of lubricant should I use?

Only use water-based lubricants. Silicone or oil-based products can damage the TPE material and reduce the product's lifespan.

How do I clean it properly?

Rinse the interior with warm water and mild soap after each use. Air dry completely before storage to prevent bacteria buildup.

Is it discreet for travel?

Yes, the compact 110 × 70mm size and neutral white/blue design make it travel-ready and easy to store anywhere.

Which channel should beginners start with?

Start with Channel A for initial desensitization. Once comfortable, progress to Channel B for more intensive endurance training.

How often should I replace it?

Replace when the texture begins to wear down or lose its grip. With proper care, it should last several months of regular use.

My Fun Trainer won't turn on after not using it for several months. Is it broken?

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.

    More control, less rush

    This really helps with pacing. The inner channels guide movement naturally, so... you’re not constantly adjusting. Definitely feels intentional, not just for quick release.

    Honestly… this surprised me

    Not gonna lie, I didn’t expect much at first—but wow. The motion feels smooth and consistent, and it actually helped me last longer. After a few sessions, yeah, I could really feel the difference.

    Partner noticed the difference

    We've used it a few times for prep, and she says things last longer now. Comfortable grip, no spots or discomfort. Charges fast and stores discreetly.
