Pleasure You Can't Stop Talking About

"Best purchase for my relationship"
Bought this for my boyfriend and wow... the difference is night and day. He was embarrassed at first, but now he's confident, and we're both enjoying longer sessions. The science behind it makes sense, and it's working!

"Finally something that actually works"
I have been using this for about 3 weeks now and am honestly shocked at the results. The dual-channel thing isn't just marketing - Channel B is intense! Started with A and worked my way up. My wife noticed the difference last weekend 😏 Compact size is perfect for travel, too.

No complaints here. The waterproof feature is clutch for shower use. The material feels premium, not cheap like some others I've tried. The only downside is wished it came with more lube samples.

"Game changer for confidence"
Look, I was sceptical about the "training" aspect, but this thing delivers. Three stages make sense - you progress naturally. The texture feels incredibly realistic. I've been using it for a month and seeing real improvement in lasting power. 10/10 recommend.

Solid product. Easy to clean, discreet packaging. Channel A is good for beginners, but B definitely steps it up. The only issue is that the white colour shows everything. Maybe a darker option next time?

Gets the job done. Compact, easy storage. Texture is nice but not mind-blowing. Training aspect works but takes patience. Good value for money.

"Finally found something that helps!"
I struggled with PE for years and tried everything. This is the first thing that's actually helped build my stamina naturally. No pills, no weird side effects. The dual channels let you progress at your own pace. I highly recommend it to anyone dealing with this issue.

Bought for my husband. He's been using it consistently and I can definitely tell the difference! He seems more confident too which is a bonus. Easy to clean and store discretely.

"Skeptical but impressed"
Wasn't sure about the whole "training" concept but decided to try. Actually works! The physical desensitization method is genius. No side effects like pills. Takes dedication but results are real.

Quality is top notch. TPE material feels amazing. Both channels offer different experiences. Been using for a month and definitely lasting longer. Confidence is through the roof now!

"Revolutionary design"
The dual channel concept is brilliant! You can literally feel the difference between A and B. Started conservative with A, now confidently using B. Results speak for themselves - lasting much longer now.

Works as advertised. Realistic feel, good build quality. The training aspect requires consistency but it's worth it. My partner notices the improvement for sure 😊

This has been a relationship saver, honestly. The progressive training system works if you stick with it. No more embarrassing early finishes. My confidence is back, and my partner is thrilled!

Perfect size for travel. TSA never questions it lol. Material quality is excellent - feels real. Channel B is seriously intense, start slow! Results are legit after consistent use.

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.
