The Crave Duet Flex is a sleek, dual-motor USB-rechargeable vibrator designed for powerful external stimulation. Building on the iconic tip shape of the original Duet, the Flex version adds greater flexibility at the tips so you can contour them precisely around the clitoris, vulva, nipples, or the underside of the penis head. With two motors working simultaneously, the Duet Flex produces deep, rumbly vibrations across a broader surface area than a single-motor toy. Choose from 4 vibration levels and 4 vibration patterns, all controlled via an intuitive button interface. The body-safe silicone outer shell is fully waterproof, making it equally at home in the bath or shower, while the die-cast zinc nickel-free inner body gives the toy its satisfying weight and durability. Charging is effortless — remove the cap at the base to reveal the built-in USB plug and connect to any standard USB port for a full charge in approximately 1–2 hours. At just 4.09 inches long and 0.58 inches thin, it slips easily into a bag for travel without drawing attention.

Intensity & Experience Level
Level: Beginner to Intermediate | Sensation: Rumbly / external vibratory
The Duet Flex's 4-level power ramp makes it welcoming for first-time vibrator users while offering enough intensity for experienced folks who crave strong, deep rumble. The flexible tips allow gradual exploration — start with one tip for lighter stimulation and work up to dual-tip contact as comfort grows.
Who is this product for?
- External stimulation enthusiasts: Anyone who craves precise, rumbly vibrations delivered across a broader surface area will find the dual-tip design deeply satisfying.
- Travelers and on-the-go users: The built-in USB plug, compact size, and waterproof build make it a low-fuss travel companion — no loose cables or batteries needed.
- People with decreased sensitivity: The dual motors and concentrated vibrating tips allow targeted stimulation across multiple erogenous zones, including nipples, the underside of the penis head, and the neck.
- Couples: Its slim profile fits comfortably between bodies during penetrative sex, providing added clitoral stimulation without interrupting intimacy.
- Curious beginners: Four escalating power levels mean users can start gently and build confidence at their own pace before exploring the pattern modes.
How to use the Crave Duet Flex?
- Charge: Remove the protective cap at the base to expose the built-in USB plug. Insert it into any standard USB port. Allow approximately 1–2 hours for a full charge, then replace the cap.
- Choose your lubricant: Apply a water-based lubricant to the tips — silicone-based lubes will degrade the silicone surface. Try a drop between the two tips for intensified sensation.
- Power on: Press the button interface to turn the toy on. Cycle through the 4 vibration levels to find your preferred intensity before exploring the 4 pattern modes.
- Position the tips: Place the flexible tips around the clitoris, vulva, nipples, or the underside of the penis head. Gently bend the tips to better contour your body's shape.
- Comfort checkpoint: If both tips feel too intense, try using just one tip for side-focused stimulation. This is also ideal for gradual buildup or for users with higher sensitivity.
- Experiment with positions: Try face-up solo play for precise clitoral focus, use it between bodies in a partnered missionary position, or sit at the edge of the bed to experiment with placement and pattern changes freely.
- Stop and power down: Press and hold the button to power off. Rinse or wipe down the toy immediately after use before storing.
Techniques & ways to play
- Solo warm-up: Run the Duet Flex under warm water for 1–2 minutes before play — the waterproof silicone holds gentle heat, enhancing comfort and sensation from the first touch.
- Solo precision: Lay back and hold the toy with one hand, using a single tip along one side of the clitoris for focused, gradual buildup before centering both tips.
- Solo body mapping: Explore beyond the genitals — try the tips on nipples, the inner thighs, or the back of the neck to discover your most responsive zones.
- Partnered penetration: Place the Duet Flex between bodies during missionary or other face-to-face positions for simultaneous clitoral stimulation during penetration.
- Partnered oral play: One partner holds the toy as a teasing addition during oral sex — its slim build fits seamlessly without getting in the way.
- Dom/sub dynamic: The partner in the dominant role can control the button cycling — deciding which pattern and level is used and when. Agree on a safeword or signal before any escalation in intensity or restraint.
Pairs well with / Complete the scene
- Water-based lubricant: Essential for protecting the silicone surface and maximising tip sensation — a must-have alongside this toy.
- Toy storage pouch or case: Keeps the silicone free from lint, dust, and contact with other materials between uses.
- OhNut wearable buffer: If penetrative sex is painful, OhNut can be worn to limit depth and reduce discomfort during partnered sessions where this toy is used alongside penetration.
- Body-safe toy cleaner spray: A quick-dry toy cleaner makes post-session cleaning fast and thorough, especially when warm water and soap aren't immediately available.
- Collections to explore: External Vibrators, Couples' Toys
How to clean and care
Cleaning: After every use, wash the Duet Flex with warm water and mild soap, or spray with a body-safe toy cleaner. The toy is fully waterproof, so it can be rinsed under running water without concern.
Drying: Pat dry with a clean, lint-free cloth and allow the toy to air dry completely before storing. Make sure the charging port cap is replaced once the toy is fully dry.
Lubricant compatibility: Use water-based lubricants only. Silicone-based or oil-based lubricants will break down the silicone outer body over time and should be avoided entirely.
Storage: Store in a cool, dry place — ideally inside a dedicated storage pouch or container and kept separate from other toys to prevent material-to-material degradation. Always store with the charging cap in place to keep the USB port free from lint.
Additional information
The Crave Duet Flex is rated as a consistently satisfying, versatile toy that performs well across a variety of moods and sessions. Its dual motors and broad-contact tips make it particularly well-suited for people who experience decreased genital sensitivity, as the vibrations can be effectively applied to other erogenous zones including the underside of the penis head, nipples, and neck. The built-in USB charging plug keeps the form factor minimal and travel-ready. The toy is for external use only and is not suitable for anal use. It is not designed for internal vaginal insertion.
Special considerations / warnings
- Mobility requirements: Using this toy comfortably requires hand and arm mobility, sufficient dexterity to operate the button controls, and the ability to reach the genitals or target erogenous zones. Users who need assistance with positioning or plugging in the charger should arrange for support beforehand.
- Charging port care: Always store with the protective cap covering the USB plug to prevent lint and debris from entering the charging port, which can affect charging performance over time.
- Silicone care: Never use silicone-based lubricants with this toy — they will degrade the outer silicone body and shorten the product's lifespan.
- External use only: The Duet Flex is designed exclusively for external stimulation. It is not anal safe and should not be inserted into any body cavity.
- Nickel sensitivity: The inner metal body is nickel-free and should be safe for those with nickel sensitivities; however, if you have a known metal allergy, consult a healthcare provider before use.
- Vaginal dryness note: If you experience vaginal dryness or discomfort, use a generous amount of water-based lubricant. Vaginal dryness is a physiological condition unrelated to arousal level.
- Medical flag: If you have a pacemaker or other implanted electronic device, consult a medical professional before using any vibrating product.
18+ only. For consensual adult use.
