I bought this contraption feeling skeptical about its proposed effects. Day 1-3: about 10v, no effect. Day 4-6: about 15v, notice less consistent sweating throughout the day, but sweat comes in uncontrollable bursts during the most unexpected times (e.g., when eating). Day 7-10: about 20v, no sweating on palm & between fingers at all, occasional sweat formation on top of fingers. Day 11-now: maintain 20v, doing 2 times a week.
In all, give it approx. 2 weeks to take full effect, now I notice no sweating even in situations where I usually sweat (e.g., driving). Occasionally sweat still forms on the side/top of fingers but less intense than before treatment. But still unable to reach the maximum 40v.
Having sweaty palms and feet was an insufferable experience ranging from social encounters to doing things like writing, using the laptop or sewing. This meant having a slippery and wet feeling a lot of the time. After 7 days of usage, the sweating has almost disappeared save for the tips of the fingers and toes. The solution provided by Raynatics was to put more water into the tray to ensure that the tips could be submerged. While I did encounter some unbearable itchiness from the first few days of the treatment and now slightly dry hands, I’ll take this over having overly moist hands and feet! Really and truly life changing!
