New treadmill, total usage of the device is only 5 hours. It has a front fan, high and low speeds, hydraulic for the belt and a belt protector for the knees and friction for the person walking on it + high protection. Rear hydraulic feature raises and lowers the treadmill with high safety so that children are not harmed. No one should undervalue the price, the device is new and I vouch for it. And no one should come unless they are serious about buying.
