these are medically helpdul & reasonably priced but to make them last longer i highly recommend storing them in the fridge between sessions, cleaning the body area of attachment & wiping the electrodes when you take them off, before storing.
I received the machine yesterday and have used it 5 times on my newly replaced knee. Everything is working properly and I am confident that it will make a huge difference in my recovery. The one thing I would suggest you include in the carry case is a few picture samples of how the pads should be placed on the various injuries/areas. I had to refer to the manual of an older machine I once used to refresh myself on the positioning.
It has been amazing. I'm able to get up and walk for a change without the pain. This was only one day after using it. I'm glad my son-in-law got this for me. THANKS a MILLION.
After one day of use I have felt a little pain relief from my sciatica. It is a good tool that compliments my PT and medications as part of a complete regimen.
