Its integrated design uses a flexible suction system, a vibrating inner channel, and built-in heating to provide multiple types of stimulation through a single male pleasure toy.\u003c\/p\u003e\n\u003ch3\u003eSucking and Vibration in One Device\u003c\/h3\u003e\n\u003cp\u003eUndertow combines 10 suction settings with 10 vibration settings, allowing the two stimulation functions to work together for a more varied experience. A built-in high-power pump rapidly changes the air pressure inside the device to create adjustable suction, while the vibration system adds rhythmic stimulation through the internal channel.\u003c\/p\u003e\n\u003ch3\u003eFlexible Internal Channel\u003c\/h3\u003e\n\u003cp\u003eThe internal channel features four different structural areas designed to create changing sensations as the device is used. The channel includes 10.5 mm progressive sections, a 13.5 mm spiral section, 5.5 mm textured sections, and an 18 mm simulated vacuum chamber. These different internal structures create changes in pressure and contact throughout the experience.\u003c\/p\u003e\n\u003ch3\u003eApp Control and Adjustable Stimulation\u003c\/h3\u003e\n\u003cp\u003eThe smart control system allows the device to be operated through a compatible smartphone app. Three adjustable levels are available for the combined suction and vibration modes, giving users control over the stimulation intensity from their phone.\u003c\/p\u003e\n\u003ch3\u003eIntegrated Heating\u003c\/h3\u003e\n\u003cp\u003eThe built-in heating function adds warmth during use, creating a more comfortable temperature alongside the suction and vibration functions.\u003c\/p\u003e\n\u003ch3\u003eDesigned for Easier Cleaning\u003c\/h3\u003e\n\u003cp\u003eThe device uses a detachable design for cleaning. The inner sleeve can be removed directly and turned inside out, allowing both the inside and outside surfaces to be rinsed more easily. The construction uses ABS and silicone, with no plastic ring around the silicone inner sleeve.\u003c\/p\u003e\n\u003ch3\u003eHow to Use It\u003c\/h3\u003e\n\u003cp\u003eUndertow is designed for solo use. Insert the appropriate amount of water-based lubricant into the internal channel, select the desired suction, vibration, and heating settings, then adjust the stimulation through the compatible app. After use, remove the inner sleeve and rinse the washable surfaces thoroughly before allowing them to dry completely.\u003c\/p\u003e\n\u003ch3\u003eWho It Is For\u003c\/h3\u003e\n\u003cp\u003eUndertow is suitable for beginners who want multiple stimulation functions in one male masturbator, as well as experienced users who prefer adjustable suction and vibration. It can also suit users who want smartphone-based control and a rechargeable design for more convenient operation.\u003c\/p\u003e\n\u003ch3\u003eWhat It Feels Like\u003c\/h3\u003e\n\u003cp\u003eThe suction creates an air-pressure-based sensation that can range from lighter stimulation to stronger pressure, while the vibration adds rhythmic and pulsating sensations through the internal channel. The flexible inner structure provides changing contact as different sections of the channel are engaged. Integrated heating adds warmth to the overall experience, while the device operates at a rated noise level of up to 60 dB.\u003c\/p\u003e","brand":"GALAKU","offers":[{"title":"White","offer_id":56163569271106,"sku":"GK2527X7","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Purple","offer_id":56163569303874,"sku":"GK2527X7","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/7271\/3026\/files\/galaku-undertow-sucking-vibrating-male-masturbator-app-controlled-11.jpg?v=1789302766","url":"https:\/\/yolovetoys.com\/zh-hant\/products\/galaku-undertow-sucking-vibrating-male-masturbator-app-controlled","provider":"YOLOVE Toys","version":"1.0","type":"link"}
