I bought this for my elderly father who had Sciatica and it does seem to be helping him. I've got to say he made me laugh when he asked if I would buy him another one for his back. He has Dementia and gets a bit confused. I said I'd love to see you try and fit one of those to your back and proceeded to examine about the Sciatic nerve and that's why it goes on your leg. I'm just pleased it's helping him.
Great. Seems to work as expected. But does get itchy when weather is hot.
I bought a wrap for me and my son and they both worked perfectly.
great service with you will be back
