lentra Hot Hand Warmers Heat Pack - 80 Count - 11 Hours Long Lasting Natural Safe and Odorless Single Use Air Activated Heat Packs for Hands, Toes and Body - TSA Approved

I purchased these to use when doing a winter camping trip, and they did not disappoint. A couple of years ago, we did a cold-weather camping trip, and using hand warmers kept me from freezing my butt off. I put one in each of my socks, held one in each of my hands, and placed a couple under my arms. This year, when we were planning the trip, there was a snowstorm forecast, and we knew that the temperature was going to be very low so I went looking for a big box of handwarmers.I found these, and wasn't familiar with the brand, but decided to give them a shot. They work very well, and kept me warm through the night. Another camper had forgotten to bring his cold weather shoes, so his feet were really cold, so I gave him a handful of these to put in his shoes, and they kept him toasty warm.They do take a few minutes to heat up, but that's not a deal-breaker at all. They are oxygen-activated, so shaking them, and kneading them makes them warm up a bit faster. Overall, these are great!

Used a heat pack as a trial on one of a cooling day before my travelling trip, and I couldn’t feel much heat generated from the heat pack... it’s a bad buy.

Bought them for the kids so they are really handy and packaged in two's, they do take about 10 to 15 minutes to come in heat. They do last about 4 to 6 hours. They don't heat up to intense like others but I'd say maybe 25% less than name brand but its not really much.

Bought a big box last year and am almost out. I love these things. I don't know why anyone is having issues with these. Maybe they don't know how to use them. I like to open them 5-10 minutes before heading outside to give the chemicals time to react to the air. I shake them and knead them a bit then finish my morning routine. I put them in my mittens/gloves/or coat pockets (never jeans pockets as that tends to get unbearably hot) and head to work. When we are about to get hit by a winter blast I hand them out to homeless people and they are so grateful. It's a huge box and more than I can use in a year so why not.The hand warmers are perfect and last much longer than I have need for them so I pass them along to school crossing guards and Salvation Army bell ringers. When they start to fade. Often times a bit of kneading is all it takes to revive them. The best part is they are so much cheaper than the competition and work just as well. I hate that the others no longer sell them in pairs. This was why I bought these last year. No regrets.

I was a bit leary given the price, especially when compared to the expensive name brand, but I’m pleasantly surprised by these…ESPECIALLY at this price point. Sizewise, they’re comparable to the more expensive brand and heat up just as quickly upon opening the package. They have zero odor/smell to them. They last for hours…in fact, my husband feel asleep with them in his hands and when we woke up the next morning we had to hunt around thru the sheets for them and sure enough they were still a bit warm 😲. Perfect for elderly folks, especially in the wintertime. My husband uses these a lot in the winter because (a bit of TMI here) I am 52, going thru all kinds of hormone changes and like the thermostat to be MUCH cooler than he does. He’s a pretty good sport about it…most of the time. He sometimes walks around in a hoodie (pulled over his head, and carrying around these hand warmers (he can be a bit dramatical 🤭). I always have them in my car during the winter month, just because you never know. Perfect for outdoor sporting events and concerts, depending on the time of year. Definitely recommend giving these a shot before dropping twice as much (or more) on the other brand. 👍🏻
