MR.ICEMR.ICE 7/14/20/40 Packs Body Warmers Large Pads for Women Men Kids, with Adhesive Backing Gives 12 Hours Warm (5.1" x 3.7"), Big Heat Sticker for Camping Hiking

I am very pleased with the body warmers. I don't use them for the cold weather; instead, I use them for chronic muscle pain. The reasons that I am giving this product a 5-star review are as follows:1. It's effortless to peel off the back paper.2. The body warmer is long-lasting.3. The price is very reasonable.4. Hides under my clothes so I can use it at work.It takes about 15 minutes for the patch to warm up. It's not super hot but just provides enough warmth to sooth achy muscles. What amazes me is that the patch lasts about 24 hours. It's usually still warm when I throw it away.

The locomotive does not have heat. The metal does not warm up fast. The warmers work great giving me some heat. Being a native Floridian we don't handle the temperature drops too well. These work great.

I bought these to use on a knee injury to help with the stiffness. It sticks pretty well but it didn’t get as hot as I expected, just a little warm.

The product wouldn't become warm. Not satisfied with their performance

I use these for my health, I live in Hawaii so it's not because of the weather. They warm fairly quickly and are not too hot. The adhesive is OK but with a lot of movement and sweating they loosen up. I will buy this product again.

It didn’t heat up very well and took longer than the directions said it would take to heat up. It usually heated up after I put it somewhere warm but not for long. They serve their purpose I suppose kinda.

Good product

I'm a photographer. I use these in my gloves when taking pictures out in the cold. I also work on a horse farm and use these to keep my hands warm. They stay warm in my gloves and pockets for most of the day.I also take care of feral cats outside. I put the warmers in their outside beds on very cold winter days and nights. I put them under a light blanket and it warms their little houses. I found body warmers are best for this. But in a pinch handwarmers work great too. I sometimes put it under a light blanket under their outside beds and they cuddle up on it to stay warm. Unfortunately they are very feral and you can't get near them and don't do well in captivity or shelters. We tried. This is the best way to keep them warm on harsh winters.
