dual channel TENS machine ?

dual channel TENS machine for the body, relieves aches and pains in muscles and joints. only used a few times. in box with pads and electrodes, new pads can be easily bought if you wanted to for hygiene reasons, either online or pharmacies, this one was bought from Lloyds pharmacy so they probably do them there. unfortunately i no longer have the instruction manual, but again this can be found online to download like most things these days! any questions please ask :-)
