SunnyBay Heat Patches for Menstrual Cramp, Air-Activated Adhesive Heat Pads for Period, 130 F Warmth up to 8 Hours, Stick to Clothing Not Skin, 2.75 x3.5 inches, 10-Count

Love this product, they last a long time and do the job. Ive bought them about 3 times. Definately recommend.

I love these heat patches! I use them for the shoulders, back and belly and they stick well and stay very warm for many hours. Honestly, great for period cramps and to take them to go in case I need a quick heat source in cold rooms or cold days. I have found that if I put them under thick clothes, they can get REALLY hot, so it is great that I can modulate the heat to my needs. I recommend, these are life savers

Works just fine for the money.

These adhesive patches are the BEST thing I have found to calm my aching legs so that I can sleep soundly at night. They have also eased a chronic spasm in my thoracic area, allowing me to remain active during the day.The fact that the patch adheres to the inside of your clothing, as opposed to your skin is a big selling point for me.This allows me to position patches for my back pain by myself, in places where a skin adhesive patch is too difficult to reach. I lie my shirt on the counter and stick the patches onto the inside of the shirt, then pull it on and the heat goes to the right place!They have a tab so that you can tear them open anywhere, anytime (no need for scissors). The paper backing removes cleanly and easily…And the heat lasts for hours and hours!!I have had a patch on from bedtime until noon the next day, and it still has some heat in it. Other patches I have tried don’t even last the night.Not only is this an amazing product, but also an amazing seller.I had an issue with the adhesive in a box that I received months ago. Every patch was not sticking properly. I messaged the seller about it and not only did they send a new box, they also took the time to apologize and explain the problems that they were overcoming to prevent this from happening in the future.As a matter of fact, I was just in contact with them and they told me that they are making the adhesive even stronger!They also told me that Amazon does not let them take part in the Subscribe & Save program, and they keep the product priced as low as they can for the consumer.They have production costs, packaging and shipping costs which continue to mount, and yet the patches have remained close to the same price the entire time that I have been a customer.I don’t know what I would do without these LIFESAVING heat patches. They have truly contributed to my quality of life, and my sleep and pain management.If you are looking for a type of heat patch to ease you pain, look no further… you’ve FOUND IT!!

No issues. Received in 24 hours. The patches provide a great deal of heat versus other heated patches. Definitely make sure there is no skin contact because these are extremely hot.

Nothing wrong with product description . I wish I had noticed that you had to put them on over clothes; it's in description and on the box, so that's on me. That just doesn't work for me personally. I can't return because I opened the box eagerly while reading the box. I have to say I feel a bit silly. It never crossed my mind that you would put something like this over clothes. I can't speak to the heat intensity or duration heat is present or anything. Ill try and find someone who prefers this or doesn't care either way.

These pads are a HUGE relief! I’ve been experiencing lower back pain and was using Tiger Balm, but can’t stand the strong smell of it. I never want to go out in public wearing Tiger Balm because of the distinct scent.So, I decided to give these pads a try. I love that they are 100% Natural and made in the USA. While comparing other similar products trying to decide which one to purchase I chose this one because of that.The pads come individually wrapped and are easy to use. Just tear open the wrapper, peel off the sticker on the back and applied it to my shirt. No mess, no fuss, and most importantly no strong odor like Tiger Balm. I can easily go out in public wearing this and no one would even know I had it on if I threw a jacket over my shirt.It’s a good size and the pad warmed up instantly. The heat lasted a long time and provided some much needed relief to my lower back. Also, after the pad stops working it’s great to be able to recycle it and use the powder on my plants. It’s reasonably priced and I feel I’m getting a lot of bang for my buck. Will definitely be buying more. Highly recommend!

These heat pads are easy to use and provide right amount of healing heat. Heat lasts about 8 hours.
