Replacement Sponge Inserts

Description

It’s important to regularly replace your electrode sponges for hygiene purposes, stimulation comfort, and general effectiveness of your tDCS sessions. While sponges can technically be re-used, you will notice they quickly lose their absorption qualities, often leading to splitting and crumbling. This degradation causes uneven current distribution across the surface of the electrodes. Uneven current distribution not only greatly reduces the effectiveness of the electrodes, but can sometimes result in uncomfortable tDCS session. Users have reported effects such as tingling, itching, and sometimes mild stinging at the site of the electrodes. Therefore, it’s a good idea to replace your sponges regularly to ensure your electrodes function properly for optimal tDCS sessions. We suggest replacing electrode sponges every few sessions, with the best results occurring when new sponges are used for each stimulation session.
