Introducing the Gorilla Grip, a familiar name in calf care. Color: Gray Used only a few times, I believe it's in excellent condition. No packaging or instruction manual. From the website: * With a powerful pump that inflates the airbags, you can experience your calves being squeezed by a gorilla. Easy to use at the end of the day. * Timer: 10 minutes auto-off. Power cord: approx. 2m. Compatible size: calf circumference approx. 28-52cm. * Easy to attach, just wrap it around your leg with the Velcro. It fits perfectly for anyone and is comfortable to use. Start with a single click of the power button, and it will automatically operate for 10 minutes. The strength can be adjusted with the + and - buttons. * Lightweight for one leg, so it can be folded up small and stored compactly when not in use. Perfect for gifts.
