For use with the Alpha-Stim 100 microcurrent and cranial electrotherapy stimulator or the Alpha-Stim SCS cranial electrotherapy stimulator for cranial electrotherapy stimulation (CES). Dispensed only to registered owners of Alpha-Stim 100 and Alpha-Stim SCS stimulators. Our new CE3 Earclip holds the felt electrode in place better than ever before. No more felts slipping off because the clips are too wet.
