I've had the EMPI Select for 2 years now. Only problem I have with it is the electrodes coming apart. I'd LIKE to wear it when I work, since it goes a long ways in pain control. I don't bend all that much, but I do have to a bit. (I manage and feed dairy calves.) This isn't super intensely physical work, just carrying bottles and other stuff, but I'd like to not worry about these electrodes pulling off my back. Any suggestions?
