"I put these on in the morning before heading to work. Feels good and gives me relief to get through the day. Lasts hours loosening tense muscles, longer than many rubs. Helps my backache."

"This is a great product for menstrual pain. It's so much better than having to carry an electric heating pad to work, and it really does stay warm for eight hours!"

"Early morning sports - tennis or golf or skiing - are killers on my husband's back, so we always keep ThermaCare with us. We wear them skiing too because they keep us warm even on the chilliest days on the chairlift!"

Lory F.

"On my bad period days, no Advil or Tylenol helps...only heat. I can wear these to bed and to work and no one knows about it. I've been using these for years and they work better than ever still."

Amy M.

"Bought to take on cruise for my back since it is not recommended to bring on heating pad & these things work for hours & are awesome!!"

Amazon Customer

"We love all of their products but especially the lower back one. There are always packs of these in our linen closet and our cars. They are wonderful for when you've overdone it and need heat relief for sore muscles, but I use them just as much before going out for a full day of yard work or kayaking to keep my back loose. I love that there is nothing but heat....no drugs, no chemicals, just the comfort and benefit of heat."

"As someone with a lower back injury and neck/cervical injury I have used these ThermaCare wraps for years. They provide massive amounts of heat and I've found they stick/adhere more than adequately. They do a great job of relaxing spasms, easing the pain of strains, and have also helped when migraines work their way down to the neck. Bottom line, there many be alternatives, but for me this is THE solution. Been using them, will continue to do so. 5 stars. Unreservedly."

Xavier M.

"I was quite surprised at just how much heat and for how long these pump out. The warmth really does last for hours. Works best for the above hip area, although they are adjustable with a very lightweight velcro attachment. They are less useful for areas much above the hips because they will tend to slide down. Men might find this less of an issue.They are also the size written on the box. Average and smaller women should use a size smaller. All in all a nicely designed product."

"Keeps my back warm and flexible while I play golf. I have never had one come loose during my swing! Couldn't play without them."

Amazon Customer

"They actually make riding in a car bearable with my bad back."
