im booking this to buy at the end of this month

i wanted to try this because i found information that says this helps rebuild nerves through neuro electrical stimulation my feet tingle at night when I do a lot of physical labour in a day. im 33 and i never experienced this kind of foot pain. apparently our nerves begin dying if not given stimulation and they first give us a tingling, then burning sensation and then neuropathy can happen later on you mentioned that you got this for a friend and this one is extra. has this helped your friend deal with tingling foot pain? online someone said using it for 15 minutes a day shows results in 3 days. is this true for your friends case?

how much for this in coins? and does it have an instruction manual? never used one of these before

hy

any defect
