These heat up quickly and are easy to apply. They are thin and difficult to see under clothing. Definitely helps with cramp pain relief. They stay warm for a long time. In fact, they were still warm when my daughter was ready to remove them. They weren't horribly expensive, and the portable heat makes it worth a try. It's nice not to have to recharge a bulky heating unit made for a similar purpose.

I use these often. Great value and last very long. Ingredients passed the test . Comfortable to use. Doesn't not irritate my sensitivite skin. And very effective

Recently bought these for a trip overseas, when I didn't want to pack a heating pad. These work so well and stay hot for longer than 8 hours. The directions say not to stick directly to skin, but I did do that in a pinch one day and it worked well and stayed on, but they do get very hot so obviously I would stick to underwear and not directly to your skin.

I have Stage 4 Endometriosis and live with severe chronic pain from it. This pain is on a level that I can’t think clearly or even speak when it’s flaring up. I can’t take my pain pills on an empty stomach, so when endo pain strikes at an inconvenient time, a heating pad is my only relief. Lately my pain is during the day (it is usually mostly at night or early mornings), so I’ve been trying to figure out what to do. I work with all men and in a communal office setup, so plugging in a heating pad and stuffing it into my waistband is not possible for me. I ordered these for emergencies and used one today for the first time. I went to the bathroom and stuck the pad to my leggings and waited about 10 minutes before I felt the heat. Is it the same heat level as my heating pads? No, but I also keep my heating pads on the hottest setting. This DOES deliver enough heat to soothe, relax the muscles, and provide comfort. I came home and took the pad off to take a bath then put it back on after with my pajamas and it’s still warm! I would definitely recommend this product and I will definitely be repurchasing. For someone with chronic endo pain, this product will probably be life changing for me at work and I am thankful to have found not only this product, but a company with such incredible values and a great mission.

Offer relief and long lasting

The Best Heat Relief Patch Out There. I’ve Tried Other Brands And None Compare. The Heat Lasts For Hours And Hours. The Patch Is Thick And Not Flimsy (You’re Getting More Coverage Whereas Other Brands Get Folded Too Easily). So Grateful For The Comfort. A Must Have Product!

I have endometriosis so my periods are truly torturous. I cannot live a normal life without having a heat pack on during the day! I have been purchasing the ThermaCare heat packs which are AMAZING, but super spendy.

I use Cora's tampons which I love very much so I wanted to give these a try because the price was right. I do really like them, but they definitely don't get as hot as the ThermaCare ones but still hot enough to get the job done. I do have to swap them out more often which is okay because these are much cheaper. I usually use one morning and one night when I'm on my cycle.

I didn't realize that these don't stick to your skin at first and they are meant to go on clothes so DON'T MAKE THAT MISTAKE. The adhesive going directly on your skin does cause a pretty uncomfortable rash so totally my bad.

I love Cora and want to support them any way I can!

I love these Cora heating patches! These are my go-to during my aunt Flow visits. I get terrible cramps and really bad lower back pain and these patches help so much. I use them on my lower stomach and my lower back too. They are super easy to apply and the adhesive is sticky, I’ve never had one fallen off during the day or at night. And they actually smell good (like lavender essential oils or something) but it’s not a strong smell at all so it doesn’t bother me and no one else can smell them. They also get pretty dang hot! Sometimes I have to put them on top of my underwear because they get so hot. They work really well and they last for probably 6+ hours because when I wake up in the morning after wearing one to bed, it is STILL warm! I definitely recommend these heating patches as well as other Cora products! These won’t disappoint!

Last very long but not very much heat is produced.
