Design and Ergonomics
Weighing 0.4 kilograms and compactly designed at 20 x 18 x 12 centimetres, the MT21 prioritizes portability without compromising structural integrity. Its ergonomic handle ensures a secure grip, allowing for both handheld operation and hands-free use when placed on a stable surface. The device’s seamless, continuous design accommodates a wide range of users, while the matte-white finish aligns with contemporary aesthetics, ensuring discretion in storage.

Constructed from medical-grade Thermoplastic Elastomer (TPE), the sleeve mimics natural textures, offering a soft yet resilient surface. Internal spiral pleats and 3D particles enhance tactile stimulation, replicating lifelike sensations. The material’s hypoallergenic properties and ease of cleaning—compatible with mild soap and water—make it a hygienic choice for repeated use.

Core Functionality
The MT21 distinguishes itself through two primary modes: telescopic thrusting and adjustable friction.

1. 6-Speed Telescopic Function
A motorized mechanism drives the sleeve in a vertical motion, simulating rhythmic thrusting. Users can select from six intensity levels, ranging from gentle strokes to vigorous motion. This feature is engineered to emulate natural movement patterns, with some noting its ability to maintain consistent performance over extended sessions.

2. Friction Mode
Complementing the telescopic action, internal ridges and nodules provide localized stimulation. The silicone sleeve’s multi-layered design ensures sustained contact, while the open-ended structure eliminates size restrictions.

Both modes operate via a single control interface, enabling seamless transitions between functions. The rechargeable 800mAh lithium-ion battery supports prolonged use, with USB-C charging ensuring compatibility with standard adapters. A full charge delivers approximately 90 minutes of runtime, ideal for uninterrupted sessions.

Health and Safety Considerations
As a product designed for intimate use, the MT21 adheres to stringent safety standards. The waterproof IPX7 rating allows for easy cleaning under running water, reducing bacterial buildup. Additionally, the TPE material is free from phthalates and parabens, aligning with EU health regulations.

Users appreciate the cordless design, which eliminates entanglement risks and enhances mobility. The absence of external seams or rigid edges minimizes irritation, making it suitable for sensitive skin. For those new to such devices, the manufacturer recommends applying a water-based lubricant to optimize comfort and reduce friction.

User Experience Insights
Feedback highlights the device’s versatility and intuitive operation. Many emphasize the value of adjustable settings, with one user noting, “The ability to fine-tune speed transformed the experience—it adapts to your rhythm rather than forcing a preset pattern.” The telescopic mechanism’s quiet operation further enhances discretion, a critical factor for shared living spaces.

Durability remains a focal point. While the TPE sleeve resists wear, proper maintenance—such as thorough drying before storage—prolongs its lifespan. A minority of users suggested that the motorized components could benefit from reinforced housing, though no structural failures were widely reported.
