Sponge inserts designed by Caputron specifically for use with the Focus device electrodes. Over time the sponges within the electrodes can grow brittle and crumble, crack, or split causing an uneven distribution of current. It’s a good idea to replace your sponges often to ensure that the electrodes function properly. It is advised that you replace your electrode sponge inserts after every 4-5 uses. These sponges come dry. As soon as one applies saline solution to them, they immediately absorb the solution and expand. They work best when inserted into the rubber electrode pad first as they expand quickly when wet. They provide excellent contact with and conductivity to the application area. Show more
