I was using my owell bodycare electro-acupuncture for quite sometime now. It’s a device that you have a sticky pad to stick on one side of the arm then you use a ball point tip on parts of your palm. They have those kind of acupuncture graph for you to look at where to point on your palm to direct to which part of your body. So the indicator was fading out for quite sometime now and I was using it. Then it was almost until I couldn’t see the interface then I changed the battery. After changing the battery I found out that the current out of the device is stronger than it was on low battery.
