SunnyBay24-Pack Heat Patches for Lower Back, Wearable Air-Activated Disposable Heat Pads to use for Menstrual Period, Neck, Shoulder, and More, Up to 113 °F Warmth for Cold Body

These are very comfortable to wear, easy to use and works all day long. I received sooner then expected and well packaged. Came with a hand written thank you and a gift. I will definitely order again.

These are amazing. The belt they come with are also a huge help to readjust and ensure the heat is targeting the right spot

This product was very useful. I use heating pads/blankets every day due to chronic pain and these were very convenient. I really liked that the belts were reusable, meaning it saves quite a bit of material as opposed to similar products. You can also use the heating packets as fertilizer once you are done with them so that's even better! The heat lasts a decent amount of time so you don't need to constantly replace the heat packets.

they seem to relax my back muscles, although they take several hours to really heat up.

These heat pads heat up like no other brand I've encountered. The sticky ones are incredible because they stick and stay hot for several hours, but these come really close without the adhesive issues that come with sticking something to your skin. I use them more often than I care to admit, and have never found anything that comes close.

I had a back pain, bought this product. It is easy to use and safe, very effective. Love it.

I CAN USE ON MY SHOULDER AND BACK AND DON'T HAVE TO WORRY ABOUT ADHESIVES,

This product doesn’t work like it says on the box. Instructions say that it will heat up in 20 minutes but I waited longer and it was barely even warm. I thought it might be a dud so I tried another one but it was the same thing. It took all night to heat up. I returned the product and I will never purchase it again. If I was able to leave zero stars I would have. This product is not worth the money I paid.
