I made my own machine. There are some YouTube videos.
Get two foil pans like the type used for catering.
Get a laptop type charger where you can change the voltage. Lots on amazon. Then buy a connector that allows you to change the plug end into a clip end like you would if clipping to battery connectors.
Cut out rubber drawer liners to cover the bottom of the pan but also spill over one end for where your wrists would sit.
Put rubber on bottom of pan.
Fill with water to cover bottoms of palms or u can put you’re feet there too and fill enough to cover both.
Sprinkle in some baking soda into the water.
Attach clips of charger to top of the pan.
Then turn on.
Make sure you are not touching the foil at all it will burn you.
If you have any cuts it will hurt. Don’t put that in the water or you can try Vaseline to On the cut.
Soak for 15min then reverse the clips to clip on the opposite pan. Soak for another 15min.
Do every other day. Took about a month consistently to start working but it worked. Must do every 2-3 days to keep up or it comes back and u have to do every other day for a month again to start working again.
Some people go once a week and it works so just depends.
Don’t give up. Will be dry but better than the latter. Good luck.
