Over time the sponges within the electrodes will wear down causing an uneven distribution of current. Worn down sponges can also cause uncomfortable tDCS sessions. It’s a good idea to replace your sponges often to ensure that the electrodes function properly and provide optimal current flow. These replacement sponge inserts come 10 to a pack and fit their respective size electrode.
