At home maintenance?

I purchased the Fisher Wallace unit. I did not use it often enough to see if it worked. To make the connection to “zap” your head you have to keep the round sponges very wet for the machine to work properly. This meant water dripping down my face and neck and I found it to be a pain. I paid about $700 for it and ended up selling it on ebay for almost that amount. IMO don’t waste your money. It’s not the same as TMS. I would say it is like electronic stimulation that many drs, and chiropractors use on their patients for pain relief.
