SunnyBay Heat Patches for Body Pain Relief - Disposable Heating Pads for Lower and Upper Back - Period Or Menstrual Cramps Therapy Heat Wraps - Air Activated Muscle Heat (24 Pack)

I loved the SunnyBay Wearable Disposable Heat Patches. Not only did the heat ease my back pain, the belt was very comfortable to wear. First of all the belts fit me! :). The belt was easy to adjust so the pads were covering the sore area. I was able to put the heat pads exactly where the heat was needed. Plus the pads stay warm longer than any others I've purchase. I highly recommend this product for folks suffering with back pain. I will definitely purchase this product again.

This is my new “go to heat patch”!!! These are absolutely wonderful and the belt included (you get FOUR) are really nice and very easy to use. They’re intended for your back but with the belt you can place them just about anywhere you need the heat for pain you’re experiencing which is what I do. I have rotator pain and I can place the belt and patches just right to alleviate it. I’ve tried ALL of them on the market and I’m sticking with these. Extremely fast shipping, very friendly and courteous staff, had a question and they got right back to me AND they’re made right here in the USA which is a big plus for me! I really did purchase these and some others from the same company and this is an honest review. So, if you’re looking for heated pain relief look no further. Thank you for a great product!

So they have multiple uses as well.

The heat pads lasted a very long time, about 20 hours. The belt is much better for the pads then wearing them on your clothing. If you need to go out during the day, these work, as it's difficult to wear, your other wraps out. A good solution to having heat on your body without using the microwave or a bulky wrap. I liked them.

I received SunnyBoy 24 disposable heating pads today and tried one immediately. After an hour, it was not remotely warm. I tried a second with the same result. Then I checked each individual pad and noticed that they were manufactured on 12/11/19 and expired 11/12/21. Today is 11/15/21 so I guess I know why they don’t work. I contacted SunnyBay and here is the reply: “The manufacturer printed the wrong date on the package. It will expire in one year, 3 years from the manufacture date.” I will be returning them.

They work great,last a long time, and if I just need them for a few hours I just put them in a zip lock bag, then when I need them again , I take them out of the bag and they heat back up again. They are a quality product, last a long time, and are a much better price then the brand that I had been buying. I will keep buying them because I have a lot of trouble with my lower back pain. They really do help with the pain. They are saving me a lot of money.

I was excited to try these for easing back pain and cramping while at work. They are super easy to use and lay very flat. They give off a mild amount of heat, but if you keep them in one place long enough it does help some. And I'll take any relief I can get. And you can reuse them! If I dont use them for longer than a few hours, I just seal them up in a ziplock to use again another day.Unfortunately, I am finding that about half of the heat pads in the box I recieved do not work. On several occasions, I have opened them at work to find that they never release any heat at all. Really a shame because otherwise, these would easily be a staple in my house.

I have been using this product for a couple months and I will continue to use! I use it for my lower back and it works wonders no used to buy a kind like these from the store and they are no wheeler near as good. The heat masters long time also! Only thin I don't like is that it takes a while to heat up, but besides that, they are perfect!

The belts are comfortable, and my husband used one on his calf muscle by wrapping it around, so don't think you're stuck with only using this on your back. The heat pads themselves will last over half a day, it's fascinating. I've gotten those toe and hand warmers before, and I'll never bother with them again, they're such a waste in comparison to these. I got them for my sacroiliac joint issue, and to take camping. We have a vacuum sealer so if I'm done with the heat pack and it's still warm I can zip it up again--the particles react to oxygen so if you seal it, it'll shut off and not burn through all its fuel. That also means you don't need to agitate the pads at all, don't bust them or shake them or squeeze them or anything, just wait like 5-10 minutes and it gradually reacts to being exposed to the air.
