After receiving my pain gone pin 10.
I read the pamphlet inside .
It says do not use this pin if you have metal implants .
I have had to knee replacements .
I am very disappointed that I cannot use this pain pin .
I was so looking forward to trying this pin.
I have not used it and was wondering if I could have a refund.
Please get back to me as soon as possible 
I'm looking forward to using it. Seems very simple and straightforward. Includes a battery. The little manual is VERY well written for technical uses and cautions.
