Protect Your Investment

Don't forget to pick up a wrist strap. An electro-static wrist guard is essential when working with electronic components such as RAM and other computer components. When used, a positive skin-to-ground contact is established, preventing remittance of electro-static discharge (ESD) and potentially damaging electronics.
