The FISHER-WALLACE CRANIAL STIMULATOR (model SBL500-B) may produce better results than the CES Ultra, AlphaStim and other less expensive devices because of its complex waveform and frequencies.

The Model SBL500-B device is an electronic signal generator which is indicated for the symptomatic relief of anxiety, depression, and insomnia.

The Cranial Stimulator—allowed by the FDA to be marketed for symptom reduction in depression, anxiety, and insomnia—is a portable, battery-powered micro-current pulse generator. It is small enough to hold in one hand, and produces three biologically synchronous waveforms: 15,000 Hz, 15 Hz, and 500 Hz. The two slender electrical cables transmit current through either a small sponge that is moistened before use, or a self-adhesive patch. They are secured in place on the temples with a soft headband. Current flows between the two electrodes when the Fisher-Wallace Cranial Stimulator is turned on. The number of flashing lights on the Stimulator clearly indicates the level of stimulation, which is easily adjusted by the user. The current automatically turns off after 20 minutes. Clear instructions accompany the Fisher-Wallace Cranial Stimulator.
