Great product that could use some improvements
I bought this for chronic neck pain . I love the vibration mode , and my neck pain has lessened significantly.  The pulse mode, however,  is shocking , literally . I tried all of the levels of pulse (on weak intensity) and it shocks me every time .  I read the directions thoroughly, and I even dampened my neck as instructed . Will continue , as im must be willing to get shocked in order to find relief .
