Using this anti - static wrist strap is easy. First, put the strap around your wrist and adjust the buckle to fit comfortably. Then, connect the cord to a grounded object. While working on sensitive electronics, keep the strap on to prevent static charge build - up. Make sure the connection to the ground is always secure. When you're done using it, store it in a dry place. Avoid pulling the cord too hard or getting the strap wet. Periodically check the cord and buckle for any signs of wear and tear.
