Hand Warmers - Long Lasting Safe Natural Odorless Air Activated Warmers - Up to 10 Hours of Heat - 40 Pair

We needed some extra hand warmers for our department. Usually get some operations in the middle of winter. Buying bulk cases of hand warmers is the way to go. Package was nicely packed. Several different options available for purchase.Pros: they start to heat up nicely the second you open and expose to air. No smell to it. Doesn’t spill any of the materials from the inside. No dust. Doesn’t overheat. Lasts for several hours. A lot of different options and sizes available. We also purchased the shoe warmer for warming toes.Cons: sometimes you might need two to three for each hand if it’s very cold, needs air to activate and I’ve noticed if you have it tightly bundle with very little air it doesn’t heat up very well.Overall a very good purchase, despite the cons they still work well. Helps keep you comfortable, just the right thickness and you can take with you anywhere and also easy to store in bags to use later. Highly recommend.

I have these, a set of rechargeable hand warmers and a set of gel hand warmers. Each works just fine in different ways, but the gel-type and the electric type are good only until you run out of electricity to recharge them. (Like during that 3 1/2 day power outage I just lived through that was caused by that "bomb cyclone" here in the pacific northwest.) Even though these are one use only, they last for a long time (10-18 hours depending on several variables). They do get quite warm.They are definitely good for emergency use for humans and pets. (My 18 year old cat was seen sitting on top of a pair of them during the power outage. Her heated kitty bed was off, I was refusing to be her mattress all day, and she was cold.) Having a hand-warmer that does NOT require electricity to recharge means that your solar charger (should you have one) can be used for more critical items like lights & communication devices.These would also be good for camping and other places where electricity is of limited supply.I also saw them being passed out at the local food bank. Not everyone has electricity to start with, or heat either.

The packages have starters to make it easy to tear open one or both pouches. I like that I can open only one if I don't need two. It takes a little bit to warm up, but then it's toasty and keeps me warm for many hours. At first, I would only use them if I knew I'd be outside for a long period of time, but now, I find them useful indoors too. I usually start by opening one or two to warm up my robe pockets on a cold morning, then I put them in my coat when I take a walk on a cold day, then I'll transfer them to a sweater pocket and eventually tuck them into a blanket I keep outside for a neighborhood cat who looks cold when the sun isn't shining. The heat lasts for a long time, and I've found it more comfortable and economical than increasing the heat for the whole house.Update 11/25/2012After reading other reviews, I am updating mine to share that the "HOT" part of "Hot Hands" seems a bit misleading. Each person has their idea of what "hot" means. These are more hand WARMERs. They feel warmer tucked into a pocket than in my gloves, and warmer still when I fold one into my scarf, around my collar. The longer I have these in my pockets, as the hours pass, the warmer they get. Rarely would I say they feel "hot". I too have found that a cup that's just had boiling water poured into it is feels hotter, but I can't tuck that into my clothing, plus in short order a cup of hot water cools down.In this last box of warmers, which have an expiration date of 02/15/2012, I did have a couple of duds that barely got warm; and I got a couple that got unusually hot - which is likely what most people are expecting and why there is a burn hazard warning. That warning may lead us to believe that these will ALL get "hot" but from my recent experience with the HAND WARMERS, that's rarely the case. Typically, they get very "warm" in my opinion, which works very well for me.After reading more of the complains about this product, I decided to order the hand and body size. I'm curious to see if the size of the bag influences the amount of heat produced. I am still happy with the hand warmers for my use. When I am outside, I am mobile, I don't sit so my experience may be different than most.

As someone who spends a lot of time working outdoors in New England’s brutal winter, I can honestly say HotHands Hand Warmers are a must-have. These air-activated warmers deliver up to 10 hours of heat, and they are incredibly reliable, odorless, and long-lasting. Once you try them, you’ll never go back to braving the cold without them!My daughter also swears by them—she tucks them into her pockets for extra warmth, and when her ears are freezing, she places them in the fold of her beanie. They stay securely in place, providing her with warmth all day long.These hand warmers are a must-have for anyone who works or plays outside in cold weather, and I can’t recommend them enough. Whether you’re shoveling, hiking, skiing, or just out and about, HotHands provides consistent, reliable warmth. I’m impressed by their performance and will always keep a stash on hand for the colder months!Thank you, HotHands, for creating such an effective product—I’ll never go without them in the winter!

Great for outdoor work when it’s cold. Keeps hands toasty warm
