Feeldoe Slim Blue Vibrating Strap-On by Tantus

Feeldoe Slim Blue Vibrating Strap-On by Tantus is a strapless partner vibrator made from medical-grade silicone that delivers stimulation to both partners without harnesses or straps. Its curved shaft holds naturally through body positioning, and a removable waterproof bullet vibrator adds customisable sensation. Designed 10% lighter than previous models, it suits couples seeking uninhibited connection and natural movement.

What you're getting

Feeldoe Slim Blue Vibrating Strap-On by Tantus is a partner vibrator made to stimulate both people during shared sexual activity without requiring a harness or external support system. The curved silicone shaft is held in place by natural body tension and movement, freeing your hands and attention entirely for your partner. It sits among the category of vibrators that prioritise dual sensation and couple-focused design.

What distinguishes this model is its weight reduction and removable vibrator element. The silicone is genuinely flexible—responsive to your body's natural motion—yet firm enough to maintain position without adjustment. The included waterproof bullet vibrator slides into the base and removes just as easily, so you can shift between vibration and non-vibration sensation within a session. Nothing blocks your movement or requires repositioning during use.

Notable features

• Strapless architecture: Held by your own body positioning and movement, eliminating the need for harnesses, straps, or external equipment that can interrupt connection.
• Anatomically curved shaft: made to align with natural body contours and deliver targeted stimulation to both partners simultaneously during penetrative play.
• Lightweight construction: The 10% weight reduction compared to earlier Feeldoe models means less physical strain and easier maneuverability during extended use.
• Removable waterproof bullet: Single-speed vibration powered by three LR44 batteries; remove it anytime to change sensations without taking off the entire toy.
• Medical-grade silicone: Non-porous, hypoallergenic material that resists bacterial growth, tolerates high temperatures during cleaning, and outlasts cheaper silicone formulations.

The detail

• Dimensions: Curved shaft approximately 17 cm in length and 3 cm in diameter; base width designed for comfortable positioning against the body.
• Material: Medical-grade silicone throughout; removable vibrator has a plastic battery compartment sealed against water ingress.
• Weight: Approximately 110 grams, significantly lighter than previous Feeldoe iterations for reduced fatigue during use.
• Power: Three LR44 button-cell batteries power the single-speed bullet; battery life approximately 2–3 hours of continuous vibration.
• Waterproof rating: Vibrator component is fully waterproof; silicone shaft is water-resistant but not designed for submersion.
• Box contents: One Feeldoe Slim Blue vibrator, one removable waterproof bullet vibrator, three LR44 batteries, and care instruction leaflet.

First use and settings

Insert the three LR44 batteries into the removable bullet vibrator before your first session—the compartment closes with a simple twist, and a light indicator confirms power is live. With your partner, experiment with positioning: the shaft sits naturally when you're standing, kneeling, or lying down, and slight hip movements keep it stable. The single-speed control on the bullet means you press once to activate vibration and again to stop; there is no dial, so intensity remains constant.

Begin without vibration to establish comfort and positioning, then insert the powered bullet when you are both ready. The sensation builds gradually; most people find single-speed vibration more than sufficient for the broad stimulation this toy delivers. If you want to explore complementary sensations, ticklers can add texture during partnered use. Always apply water-based lubricant generously before insertion, especially on your first attempt, since the silicone grips naturally and does not self-lubricate.

Care and storage

Wash the silicone shaft with warm soapy water immediately after use, paying attention to the base where lubricant accumulates. Rinse the removable vibrator briefly under running water only—never soak it—and pat dry with a lint-free cloth. Store both components separately in a cool, dry place away from direct sunlight and extreme heat. Silicone does not need talc or renewal powder and should never contact petroleum-based lubricants, which degrade the material over time.

Dig deeper

Partner vibrators work best when both people communicate openly about positioning, pace, and sensation beforehand. Understanding how your bodies fit together and where stimulation feels strongest takes one or two attempts; that is normal and not a sign the toy is wrong for you.

What to expect

On your first use, the strapless design feels noticeably different from harness-based toys; your body holds the shaft in place through natural tension rather than external support. Most people find this liberating once they adjust to the positioning, usually within one or two sessions. The curved shaft does align well with internal anatomy when positioned correctly, and the light weight means you will not feel fatigued even during longer play.

The removable vibrator works smoothly; inserting and removing it takes seconds, and you will quickly learn whether you prefer vibration throughout a session or only during specific moments. Battery life is genuine—three LR44 cells power roughly two to three hours of continuous use. The silicone itself holds up well to vigorous movement without degrading, and waterproofing of the vibrator component remains intact through repeated cleaning.

First-time users sometimes worry the toy will slip out during active movement; body tension and natural moisture hold it far more securely than you might expect. Genuinely loose fit is rare unless the shaft diameter does not suit your internal anatomy, in which case you will know by session two. The single-speed vibration delivers broad, rumbly sensation rather than pinpoint intensity, which suits the toy's dual-partner design but is worth knowing if you usually prefer targeted stimulation.

Cleaning is straightforward, and the silicone resists staining or odour when dried promptly. The removable vibrator does occasionally need a new battery set, but replacement LR44 cells are inexpensive and widely available. Overall, this is a durable, low-maintenance toy that performs consistently across many sessions if cared for properly.
