The Changjiang No. 7 Automatic Male Masturbator is designed to provide a customizable and immersive experience through its advanced set of features. Equipped with 15 thrusting modes, 4 suction levels, and 9 vibration patterns, it offers a wide range of adjustable settings to suit individual preferences. The device also includes a built-in heating function, which gradually warms the internal chamber to a comfortable, body-like temperature, enhancing the overall sensation during use. Additionally, its integrated sound function provides soft, rhythmic audio feedback for a more engaging experience.

The sleeve features a soft, skin-like exterior and a firm inner core that work together to create a natural and balanced tactile experience. Internally, the canal is structured with varied textures and zones that replicate different levels of stimulation, including ribbed areas and tighter sections to provide a lifelike feel from entry to finish.

A user-friendly LED display allows for easy control of the various settings, making it simple to adjust modes in real time. The device is also equipped with a strong suction base that securely attaches to smooth surfaces, allowing for hands-free use or integration with compatible harness systems.

For best results, it is recommended to use this product with a water-based lubricant, as silicone-based formulas may damage the material. After each use, the sleeve should be thoroughly cleaned with warm water and a mild antibacterial toy cleaner, then dried completely before storage. To maintain its quality, the product should be stored in a cool, dust-free location away from direct sunlight and other silicone items.

This thoughtful combination of features makes the Changjiang No. 7 a versatile and user-focused product, offering both comfort and functionality in a sleek, modern design.
