【Electric Pulse Technology】This is an Electric Pulse neck massager, NOT a traditional physical kneading or Shiatsu massager. It utilizes low-frequency electrical impulses combined with soothing heat to stimulate neck muscles. It has no moving parts, offering a unique, vibration-free relaxation experience. 【Crucial Prep for Maximum Comfort】 To avoid any sharp tingling or "shock" sensations, proper skin preparation is essential. Please use the included hydrogel pads OR wipe your neck with a damp towel to keep the skin slightly moist before use. Always start at the lowest intensity (Level 1) and gradually increase as your neck adapts to the pulses. 【Ultra-Compact & Wearable Design】 Designed for ultimate portability, this massager is intentionally crafted to be sleek, lightweight, and smaller than bulky traditional massagers. Resting on your neck as lightly as a pair of headphones, its mini size makes it your perfect, unobtrusive companion for the office, daily commutes, or travel. 【Customizable Modes & Soothing Heat】 Personalize your relaxation with 10 pulse modes and 16 intensity levels. The integrated heating function gently warms your neck, enhancing the electric pulse effect to help melt away daily stress and stiffness. 【Cordless Convenience & Thoughtful Gift】 Featuring a quick-charging universal USB-C port, it provides up to 2 hours of cordless use per charge. This highly portable, feature-rich pulse massager makes a wonderfully practical gift for friends, partners, and family members who spend long hours at a desk or on their phones.
