These are not worth the low price.
The baggies they come in are pretty cool. If only the electrodes contained within were not of the worst quality I have experiencedz I have 1.5 years of needing transdermal e. nerve stim in order to bear the pain if walking with my spine all jacked. these are  The worst! They are gooey sticky yet barely adhere to the skin... had to use electrical tape to get em to stay w/out shocking me... now if unlike me you remain stationary  for the stim as well as don't need them on constant it may still be a good buy... but maybe no cuz re-using these pads isn't really an option... & they leave gooey goo boogars on ya... Party foul & for shame electrodes for shame!
