First Impressions

The Lelo F2S represents a bold step forward in male pleasure technology, combining app-controlled vibrations with an innovative open-ended design. As someone who's tested dozens of strokers, I was intrigued by its dual-motor system and AI responsiveness - features typically reserved for premium vibrators. Priced at $199, it positions itself as a luxury item for tech-savvy explorers rather than a simple gratification tool.

What sets it apart is its medical-grade liquid silicone sleeve with pronounced ridges that create surprising texture. Unlike traditional enclosed masturbators, the F2S's open design allows for adjustable tightness by simply applying pressure to the sleeve. After three weeks of testing (and several firmware updates), I've formed some strong opinions about where this toy excels and where it frustrates.

Design & Comfort

Unboxing Experience

Unboxing the F2S feels like unveiling a premium tech gadget. The matte black aluminum alloy body has subtle faceted edges that provide secure grip even when slippery. At 8.5 ounces, it's lightweight enough for prolonged use but has satisfying heft that conveys quality.

The liquid silicone sleeve deserves special attention. Its oval-shaped interior (measuring 1.3" at the widest point) features aggressive ripple patterns that remain noticeable during use - a stark contrast to softer TPE sleeves that lose definition under pressure. While initially firm, the material warms slightly with body heat after 5-7 minutes of use.

Ergonomics

The open-ended design solves two common stroker frustrations:

1、No suction-related discomfort

2、Easy cleaning (just rinse under water)

However, this design demands more lube than enclosed toys. I recommend applying a quarter-sized amount every 10-15 minutes to maintain smooth gliding.

Real-World Performance

Solo Sessions:

The learning curve is real. My first two attempts left me underwhelmed - the tight sleeve felt numbing rather than pleasurable. Breakthrough came when I:

Used twice as much lube as recommended

Started with just the front motor at 30% intensity

Let the AI mode "learn" my movement patterns

Once dialed in, the textured ridges create a kneading sensation unlike any vibrator I've tested. The open design allows for perfect pressure adjustment - squeeze lightly for gentle stimulation or firmly for intense vibrations.

Partnered Play:

The app shines here. My partner enjoyed:

Creating custom vibration "playlists"

Using the touch-sensitive control during foreplay

The long-distance functionality (tested up to 15ft through walls)

Downside: The toy's noise level (45dB) makes discreet public use challenging despite claims of being "whisper quiet."

Pros & Cons

Pro Tips

Optimizing the Sleeve

1. Lube Smartly – Use a thick hybrid lube (like Sliquid Silk) for longevity. Apply a quarter-sized amount inside the sleeve and a dime-sized drop on yourself before insertion.
2. Break It In – For the first 3-4 uses, focus on gentle strokes to soften the silicone slightly—this reduces initial overstimulation.
3. Pressure Control – The open design lets you adjust tightness. For broader stimulation, grip loosely; for focused intensity, apply firm pressure near the base.

Mastering the Tech

4. Create Presets – Save 2-3 custom vibration combos in the app (e.g., "Slow Build" or "Edge Mode") to skip menu navigation during use.
5. AI Mode Tweaks – The system learns over time. For best results, use consistent thrusting rhythms for the first 5 minutes to calibrate responsiveness.
6. Disable Notifications – Turn off app battery alerts and messages to avoid disruptive pop-ups mid-session.

Hybrid Play Techniques

7. Partnered Play – Have your control the app’s "Touch Mode," where their screen taps translate directly into vibration pulses.
8. Synced Content – Pair with erotic audio tracks—the vibrations will modulate based on sound frequencies for immersive experiences.
9. Temperature Play – Warm the sleeve in water (up to 104°F/40°C) before use for enhanced realism.

Maintenance Hacks

10. Deep Cleaning – Use a soft-bristle toothbrush to scrub ridge crevices weekly, then sanitize with a 10% toy cleaner solution.
11. Storage Trick – Insert a silica gel packet into the sleeve when not in use to prevent moisture retention.
12. Battery Care – After charging, unplug within 2 hours to preserve lithium-ion lifespan (overcharging degrades capacity).

The Verdict

The Lelo F2S isn't for everyone - its tech-forward approach demands patience and a willingness to experiment. But for those who invest the time, it delivers one of the most customizable solo experiences available. The dual motors provide genuinely innovative stimulation that evolves with your movements rather than offering static patterns.

Best for: Tech enthusiasts, edging practitioners, and couples exploring app-controlled play. Not ideal for: Those wanting instant gratification or traditional suction sensations.

At its premium price point, I'd only recommend this to users who truly value cutting-edge features over simplicity. When everything clicks (literally and figuratively), it's magical - but be prepared for some frustrating trial and error along the way.
