My second Pain Pod. I bought my first around 10 years ago (which still works, uses the same pads and kept charge packed away in a box for about 4 years). I can now use the Pods together on different areas or with large pads on one and small on the other. (Hubby now borrows one when he needs it too!) I'm grateful that the pad wires and pads are the same connections across the range as my old wires and pads weren't in great condition any more. I am glad that there are extra large pads and the back specific pad too. Turning to my Pain Pod(s) again has helped ease chronic pain from a spinal injury and neuropathic pain from a genetic neurological/nerve condition. They are also helping to work muscles and circulation in my legs which don't work properly now. My only disappointment is that the new Pod has 2 less programs than my original. I will never be pain free, but my pain level when using Pain Pod is half that without. I am able to cut back significantly on harsh pain medication and take less rest periods each day.
