Perfect for people working with electronics or people looking to build their own computer, the anti static wrist strap is a must have item for ensuring safety when dealing with electronic products. It works by equalizing the voltage between you and the computer to avoid static sparks from damaging your hardware or electrocuting yourself. Simply fit the elastic band around your wrist and clip the alligator clip to a metal part of the computer chassis. Preferably leave your PSU plugged into the power socket (but with the power turned off) to ensure that both you and your computer remain earthed. Feel more secure about static discharge with the anti static wrist strap!
