F1s V2 Waterproof Sucking Mens Masturbator by Lelo

The F1s V2 Waterproof Sucking Mens Masturbator by Lelo is a dual-motor stroker that combines vibration with SenSonic™ sonic-wave technology for deep tissue stimulation. It connects via app to track performance and customise sensation patterns in real time. Designed for anyone wanting sensations beyond what manual stroking or basic vibration can deliver.

What it is

The F1s V2 Waterproof Sucking Mens Masturbator by Lelo is a precision-engineered stroker that delivers two distinct sensations simultaneously. A traditional vibration motor works alongside a SenSonic™ motor that produces powerful sonic waves, penetrating deep into tissue rather than stimulating only the surface. Ten embedded sensors read your response and adapt the experience in real time through Bluetooth app control, learning which patterns and intensities suit you best.

What separates this from basic strokers for men is the intelligent feedback system combined with Cruise Control™ technology. When you apply pressure during climax, most strokers lose intensity; this one detects the change and automatically compensates. The aluminium exterior houses the dual-motor system while the flexible silicone sleeve conforms to your shape, making each session feel personalised rather than generic.

The highlights

• SenSonic™ sonic waves: Penetrate your entire shaft with sensations that build progressively, creating climaxes deeper than surface vibration alone can deliver
• Dual-motor system: Vibration and sonic technology work together to target different nerve endings and create multi-layered stimulation
• Cruise Control™ technology: Automatically maintains consistent power exactly when you need it, compensating for pressure changes during peak moments
• App customisation: Bluetooth connectivity lets you programme ten different patterns and track which ones work best for your body
• Waterproof construction: Fully submersible design enables shower exploration and makes cleanup a matter of rinsing under running water

Getting started with a waterproof stroker

Charge the F1s V2 fully before first use via USB; this takes roughly two hours. Download the Lelo app and pair it via Bluetooth so you can control intensity and access all ten patterns from your phone. Apply a generous amount of water-based lubricant to the silicone sleeve—this stroker needs more slip than most because sonic waves travel better through fluid. Start with lower intensity to feel how the SenSonic™ waves differ from ordinary vibration, then gradually increase as you discover your preferred pattern.

The sleeve fits most men comfortably; the silicone stretches to accommodate variation in girth without feeling either loose or overly tight. Unlike Japanese ona holes, which rely on textured internal chambers, this one creates sensation through motor technology rather than shape alone. During your first session, spend time exploring—the app tracks which patterns you use longest, helping you understand your own preferences. Rinse thoroughly under running water after use; the waterproof design makes this straightforward.

Should you choose this one?

Care and storage

Rinse the silicone sleeve under warm running water immediately after use, using a gentle soap if needed. The aluminium exterior and electronic components are not submersible, so avoid submerging the entire unit. Pat everything dry with a soft cloth before storing. Keep the F1s V2 in a cool, dry place away from direct heat or sunlight, and charge it monthly even if you are not using it regularly to maintain battery health.

What to expect

The SenSonic™ sensation feels genuinely different from standard vibration—instead of a buzzing or trembling motion, you experience waves that seem to move through tissue. First-time users often find the sensation subtler than expected at lower intensities, which is why starting low and increasing gradually matters. Most people spend the first few sessions discovering which of the ten patterns suits them best; the app's tracking feature shows you exactly which ones you return to most often.

The Cruise Control™ technology is where this stroker earns its engineering reputation. When you apply grip pressure during climax, ordinary strokers lose power or stall; this one detects the pressure change and automatically boosts intensity to compensate. That consistency during peak moments is what separates this device from basic alternatives and is why many users describe the experience as noticeably more intense and satisfying.

Cleaning is straightforward because the waterproof design means the sleeve rinses completely under running water without any hidden crevices or seams where moisture can trap. Battery life typically runs eight to ten hours between charges depending on intensity used. The aluminium housing stays relatively cool during use because it dissipates heat from the motors, though extended sessions at maximum intensity will warm the exterior.

Men tend to get on well with the F1s V2 if they enjoy exploring settings and understanding which sensations work best for their body. Those who prefer grab-it-and-go simplicity sometimes find the app-controlled approach more complicated than they want. The larger size also means it is less portable than compact strokers, making it better suited to use at home rather than travel.
