NEUTRON SMART ROPE JUMPING DEVICE
The handle is equipped with 360-degree high-speed bearing, which ensures smooth rotation of the rope when rotating and prevents the rope from winding.
The built-in vibration motor can let you know when you're immersed in exercise, whether you've achieved your goals or timed out timely and effectively.
The rope is made of PVC material and do not worry about knots.
Unlike other jump ropes with coin batteries, ours comes with a rechargeable 300mAh Li-Battery that can last 2-3 months when fully charged. Solves frequent charging problems.
