About This

• Please Note: 1. Apply a thin layer of gel or dampen your skin before each use to ensure optimal comfort. 2.

• 8-in-1 Lower Back Massager Belt - The SKG W9 Ultra combines targeted kneading, 850nm NIR warming, mid-frequency rhythm modulation, and app-guided smart control in one wearable belt. The upgraded Φ12 motor delivers +20% deeper kneading force than the previous generation - no more switching between multiple devices for full lower back relief. Fits waist 23-47″. Tip: First-time users may feel mild tingling at lower intensities - this is normal and fades quickly.
• Titanium-Coated Lower Back Massager - Unlike back massagers using plastic or rubber nodes, the W9 Ultra features 8 TiN-coated titanium heads for smoother, skin-friendly contact that lasts longer. Combined with 3000-speed rhythmic kneading modulation, each node mimics real hand pressure deep into lumbar muscles for a layered, immersive relief experience. Best used directly against skin or over thin clothing.
• 850nm NIR Heat Relief Lower Back Massager - Most heat belts use a single red light source; the W9 Ultra runs a dual-spectrum system: 11 × 850nm near-infrared and 31 × 630nm true red light across a 20000mm² heating zone for deeper muscle warmth and more effective circulation support. Three heat levels (100°F / 104°F / 108°F) can be used independently or combined with kneading. Ideal for post-workout recovery, desk fatigue, or chronic lumbar tension.
• 8-Zone Targeted Lower Back Massager - Target exactly where it hurts with 3 motion patterns (Clockwise / One-Side / Left-Right) across 8 independently controlled zones. Dial intensity from 1-9 for gentle daily maintenance or deep tissue relief. Control everything via SKG App or wireless remote: no reaching under clothing needed. Automatic 15-minute shutoff protects against overuse. Start at level 1-3 and increase gradually.
• Cordless Lower Back Massager Belt - The W9 Ultra runs up to 100 minutes cordless on a single charge, with Type-C fast charging for daily convenience. The upgraded premium leather strap (vs. nonwoven fabric in v1.0) is breathable and adjustable, fitting waists 23-47″. Use it at home, at the office, or in the car - discreetly worn under clothing without interrupting your day.
• Award-Winning Lower Back Massager - Backed by 1,500+ SKG patents and multiple international design awards, the W9 Ultra is built for long-term quality and daily reliability. Comes in exquisite ready-to-gift packaging - a thoughtful present for parents, partners, or anyone managing lumbar discomfort.
