I'm suprised... this thing actually works!
I work infront of a computer all day and develop the occasional neck and shoulder pain.  It became excruciating enough for me to buy this questionable looking product.  I tried it... and... I couldn't believe it.  This thing actually works!<br /><br />There's some electro-conductive in the box and the pen won't work with out.  Just dab a drop of it directly on the spot that is painful.  I'd recommend putting the strength of the pen to "1" (lowest) at first, and let it shock the area at a low intensity.  Keep it there for a few minutes (and VERY steady or it  will shock other nerves around it).  The pain in the neck was instantly gone!  I half expected it to immediately come back, but so far (it's been 12 hours), there's still no pain!  I can't believe this thing actually works!
