HotHands 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 bought these hand warmers for my husband. He works year round in the cold and in the heat. I thought these would help keep him a bit warmer. In fact they do. The last a long time and warm up quick. When not in use he discovered putting them in your pocket or a Ziploc bag helps them stay heated longer. This is a great product for those who work outside or just don't like having cold hands.

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.

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.

Works great!!!!

I've used these handwarmers before, mostly when winter camping in the high desert.I decided to look for another solution, and bought a pair of rechargeable hand warmers. Tried several brands. Performance was a mixed bag, but generally they got plenty warm when kept in a pocket, but held in the open air they often struggled to keep up with the cold. When slipped into my glove, they would, at best, give off lukewarm heat. In other words, hand warmers that would keep you warm unless it was really cold out - what's the point?Next up - refillable lighter-fluid hand warmers. These were a bit more consistent than the electronic warmers, but the 6 hour version I purchased wasn't super warm either. Biggest downside is that once you start them there is no 100% safe way to deactivate them - you're supposed to let them exhaust their fuel. And where they are very low odor, if you have one of these in your shirt pocket you will get a faint scent of lighter fluid from time to time.Strike one against electronic warmers, strike two against fluid based warmers. Back to the classics for me. They put out decent heat, work well in my gloves, and I can share if I'm camping with a group. Long lasting, and even TSA approved they say.
