IRIS USA Hand Warmers Individual Warmers Pocket Warmers

I got these during a prime sale in Sept while they were 1/2 off. And, I am soooo happy that I did. These things are huge. When they say that they last for 18 hours that is exactly what they do. And, they can get extremely hot, be careful about who you allow to have them and where they will be used. An overlay would be good for the very yound and the very old for sure. The trick is to always keep them covered whether in your pocket, a sock, under the covers, etc. because if they are exposed to too much air they will cool off. If they do cool off w/I 12 hrs of opening, just shake them vigorously and place them back in your pocket and they should reheat. They are good for camping, hiking, sitting out by the fire on a cool night, off grid life, and to give away to the homeless in cold weather. I will be purchasing many more of these.

They are very warm and do stay hot for 18 hours

Kept my daughter warm during her Army boot camp night out.

This type of air powered warmer should (based on other brands) get REALLY hot - there's a reason for the warnings about putting directly on skin). But the box I got is nearly USELESS - the pads barely get warm. They're well constructed (strong, and the adhesive allows easily pulling off) but since they don't work well there's little point.

Nice to buy bulk and not have to run to the store for more all the time. They work great.

Life savers!! We went to Canada in December and the cold could be a little unccomfortable at times. These packets were perfect to help us keep warm. We would put them inside the pockets and it would help our hands stay warm.

These take some time to warm up then get hot about 2hours in stays hot about 17 hours. Before the last hours is then turning warm to cold. They do work very good price too. Yes worth it to buy.

Very long lasting heated pads .
