This is a great hyperhidrosis device. I feel it works better than my original Drionics device in which the current is more consistent. This device also has a manual mode where the current direction changes when you lift your hands and feet (create an open loop) and place your hands and feet back on. My only drawback is that this device is meant for people who have smaller hands. I have big hands and feet (12" feet) so I had to order a second device. 👍
