Kailo kit nanotech bio antenna pain patch.
If you check the price from Amazon or wherever they are very expensive. I don't know how I managed to purchase mine for under $50 is beyond me, but I could never afford the prices that are being shown everywhere now.  I did get the kit and it works fine but the Korean patches for less than $5. almost works just as well. I would try them first, I did not, but I am happy with both.
