Calf Care Single Leg Type High Power Leg Care Lightweight 3-Step Adjustment (Strong/Medium/Weak) Gray DOSHISHA The secret to the "painfully pleasant" sensation of the Gorilla High Power series is the powerful pump that rapidly inflates the airbags, even in a small package. This size still allows for authentic care. Easy to put on, just wrap it around your leg thanks to the Velcro. Anyone can use it comfortably. To start, simply press the power button once, and then let it do its work. You can adjust the strength with the [+] and [-] buttons. It's a lightweight type, so you can fold it up small and store it compactly when not in use. Perfect for gifts. The ease of use, allowing you to use it whenever you want, is also a key point. Enjoy it during your relaxation time.
