Thank you for viewing this product out of many others. This is a device that helps us achieve youth, beauty, and energy. It's easy to operate and can be used quickly anytime. It's a reliable helper. It works well for stiff shoulders, back pain, and fatigue in the legs and lower back. The strength can be adjusted randomly. Since it uses gel for treatment, there's no risk of skin abrasion or pain. Commercially available gels can be used. You'll feel refreshed after use. A dedicated case is included. You can perform the treatment yourself, but it's even more comfortable if someone else does it for you! I purchased it about two years ago. Original Price: 300,000 yen Rated Input: DC15V (100V power adapter included) Power Consumption: 21W Model: HS-7261 Case Dimensions: 410x250x100mm
