Tried these before for neck and arm and back pains. They heat on contact and are useful to have. I tend to get sore muscles every so often so this is a good thing to have around. My husbands likes to use these as well.

What do you think, have you used them?

Great way to constantly have heat on an injury

I am constantly plagued with horrible back pain, I decided to try these and I am pleasantly surprised with how well they work. They live up to their claims of 16 hours of pain relief. Comfortable to wear and easy to use, and even though they are one time use products, they are well worth the cost to have 2 pain free sessions. Would definitely purchase again and recommend.
