Due to the ongoing severity of the COVID-19 epidemic, we are temporarily suspending our operations. While we will not be accepting any orders or returns, we are available to assist current customers as needs arise.

This was not an easy decision, however we have always held a strong stance that safety is of paramount priority when it comes to Transcranial Direct Current Stimulation (tDCS). We have gone to extensive lengths to ensure our products are safe, our customers stay safe, and have even blown the whistle when finding other companies selling risky, sub-par tDCS devices. As we monitored the progression of the COVID-19 virus, we quickly realized we would be hypocrites if we ignored the situation.

For the safety of not only our employees and vendors, but our customers and society as a whole, we are suspending operations for now. These are unprecedented times, but we don't have to endure them alone. We are all in this together. From Los Angeles to Beijing, it matters not what your gender is, your race, religion, or economic status... we all can make a difference.

Please, stay home when you can. Practice social distancing, wash your hands often, and BE KIND to your neighbor. And as always, thank you for being a part of The Brain Stimulator Family :)

Amrex Professional 3×3″ tDCS Sponge Electrodes are arguably the best sponge electrodes on the market, and are preferred by many tDCS enthusiasts. Amrex Electrodes use only the highest quality materials, and are comprised of a cellulose sponge with a stainless steel metal mesh backing, enclosed within a thick, rigid, rubber casing. These electrodes are the industry standard for sponge electrode based stimulation.

You may want to consider adding replacement sponges to your order. It’s a good idea to replace your sponges regularly to ensure you receive the best results and the most comfortable tDCS sessions.  While you can use sponges more than once, we recommend replacing your electrode’s sponges as often as you can. Optimal results can be achieved by using new sponges for each session.

Looking to save some money? We recently introduced discounted replacement sponge subscription plans so you will have plenty of fresh sponges on hand when you need them.

    Worth the money. I prefer these over the new silicone electrodes. Amrex uses a rubber-like material that doesn’t grab and pull at your hair like silicone.
