The pad is incredibly versatile for grounding or blocking EMFs. You can use it in various situations at home or on the go. Choose a hard/stiff or flexible pad based on your preference and desired use. When direct contact with the earth isn't possible or you want to limit EMFs on your lap or office space, this pad will help channel the earth's energy, providing the same benefits as outdoor grounding. Both styles of the grounding laptop pad measure 12x16", are easy to use, simple to clean, and require no particular setup or installation. They come with a 15-foot straight cord that you attach with an alligator clip to the pad and then plug the other end into the grounded portion of your outlet.
