The company I get my pads from and where I got my unit from, Empi just called to see if I needed more pads so I asked them and they said no they are still in business. Yeah! Also wanted to share a hint my PT told me years ago - if after you wear the pad a few times, take and wet your finger and rub it on the gel pad and put it on the plastic storage sleeve and keep all your pads in the frig. By wetting it it renews the sticky gel and keeping them in the frig prolongs the life of them. A great tip! I use my unit on my shoulders and low back. Couldn’t work without it!
