ThermaCare Adhesvie Heat Wraps, Portable Neck & Shoulder Heating Pads & Pain Relief Patches for Sore and Stiff Muscles, HSA/FSA Eligible & Approved, (Large, 11)

Great product great price heat activated as soon as you open it the tabs are not that sticky you have to use additional adhesive tape it's because skin has oil, sweat, but the product is good . Give it a try I use the neck wraps it helps with stiffness and pain in fact I got my husband hooked he loves them . Great product!

Buy these all the time, they really help when my neck is bad, I also buy the back wraps for when I’m suffering with my back… they last all day and really help ease the discomfort.

Best non-smelly, heat generating, non-pill format healing for my aches and pains. They apparently imroved the sticky attachment because it holds in place better. I've worn all night and all day. Patch stays in place.

These Heat Wraps are great when you've overdone yard work or household chores that require stretching your arms and shoulders. You're not required to keep reheating neck and shoulder heat pads to get a good 8 hour heating session.

The ThermaCare Heat wraps are a nice tool to have. We use them for general aches and pains around the neck and back. The heating ability is nice and you definitely feel the warmth for a while, not sure that it's actually 16 hours but it's several hours. This particular one does provide adhesives to attach to different areas of the body but be aware that they are only useful once. If you remove it after applying it and try to reapply it, its ability to stick is significantly decreased. Another thing to note is that if you put it on and sweat (like go outside or do something remotely active), the sweat will cause the adhesive to lose its effectiveness too. I do also like that it's portable so I tend to travel with these when I get some aches and pains in the airplane or car. They don't take up much space.
