Large Hand & Body Warmers - Up to 18 Hours of Heat, Super Long Lasting - Easy, All Natural - Air Activated, for Body, Hands & Toes - Odorless Hot Hand Warmer - Sport Temp

Took about an hour to warm up once activated but these last a long time. I went back to my coat a few days later and the pack was still putting off heat. Great size also.

He's up very quicplease it's great for keeping you warm. I also use them to keep my cat house warm when the temperatures drop below freezing. My kitty cat seems to love them.

I am a doc student living on an extreme budget in a place that is not exactly weatherized. I have a small ceramic space heater and wear layers indoors, but that doesn't always help. I liked these because I put them under the covers at the foot of my bed 20 minutes before bedtime. I couldn't be happier to be tucked in, nice and warm. Was better? They are larger and last longer than the tiny ones that fit in your winter gloves. So, I can get in bed, do some reading or homework, then finally go to sleep and not get cold in the middle of the night because the warmers wore out.I will keep these in my camping gear moving forward. I know they will be perfect in a sleeping bag. ;)

The 18+ hour body warmers are a decent option for staying warm, though they don’t quite live up to the full 18-hour claim. In my experience, they lasted about 12 hours, which is still pretty good. However, I did notice that they work best when placed inside clothing or tucked into pockets. If I held them in my hands out in the open air, they didn’t seem to generate much heat at all.Overall, they’re effective as long as they’re used correctly. For outdoor activities or situations where you need consistent warmth, these are a solid choice and worth the money but don’t expect them to go the full 18 hours.

These are great on cold nights out or for therapy. They heat up in about 2 minutes but once they're hot they stay hot for like 3 to 4 hours then start to lose their heat. But that's ALOT of time for a little hand warmer in my opinion. I like that you get a big box full of warmers and that's plenty for your uses. Really appreciate these little heaters, they keep me warm when everyone else is freezing.

Yes, these work great. We use them for an outdoor pet. We place them under their bed cushion to help provide warmth during the overnight. There are times we find that they are still warm 24 hours later. Great longevity!!

So if you hadn't heard the news, we had a snowstorm in the South last week. And because here in the South we're not used to anything colder than 40°. I bought a bunch of these because I wanted to stay warm in case we lost power. So each night I would open a pack. We would stick it in our bed and when we went to bed our bed was so warm. These things were hot to the touch. But they made our bed so warm and they made us feel so warm as well. I highly recommend them. I was very pleasantly surprised.

I use this in this season cause I walk early in the morning and if its cold I insert them in my shoe ... works wonders keeps me warm , good value u for the money
