These hand warmers were a lifesaver during a 5-day trip to snowy New York City. I used them daily while walking around outdoors, and they consistently kept my hands comfortably warm in freezing temperatures. They heat up quickly, hold their charge well, and fit easily inside my gloves without feeling bulky. I also appreciated that they’re rechargeable, which makes them much more convenient than disposable warmers and better for long trips. Overall, these are a great option for cold weather travel, commuting, or outdoor activities. I’d definitely recommend them for anyone spending time outside in winter.

bought a pair for me and a pair for a gift. They heat up quickly and in this cold winter, may make it possible to enjoy some outside time! Small enough to fit in my palm, they should help keep my hands warm. The pattern is pretty and just a bit fun. I haven't had a chance to give them a good try, but expect they will be just right for cross country skiing or shoveling! I like that there are different heat levels you can set them to. They came fully charged, with their own charging cord

Used these yesterday and they’re perfect! Slipped into my leather gloves w/o a problem. Or, very nice warmth added to my coat pocket. Small but effective. Lowest heat setting was plenty so battery lasts longer. Charged fairly fast. Instructions are clear. No problem at a court house security check point. Highly recommend.

These little hand warmers are so adorable and keep nice and warm. I do wish the battery life lasted a little longer but overall did what I needed it to. They charged up fairly quickly and fit perfectly in my hands. They are not as big and bulky as some of the others I have seen which was another plus for me. They are also small enough to put comfortably inside gloves if needed. Overall I would recommend again.

They're cheap, seem somewhat solidly built, and get plenty warm. The biggest reason to consider them is probably the size as they'll easily fit into larger(or stretchy) gloves or mittens, the little loops can snag a bit on fabric, especially with your finger through it. The battery life seems decent, I mostly only use them for taking the dog out, who happens to enjoy staying out there a fair bit longer than I do. The only downside I can really think of that I've experienced so far is how easily you can bump the button by accident and change the heat level. I have done this several times already, mostly while they were in my gloves, which of course you can't see what level they're at without removing them. Best solution there might be for them to recess the button further or make some form of cover for it. I wouldn't want such a product to be made more difficult to operate for anyone with medical issues. In terms of prolonged use, you may want to shift it around in your hand. Personally after a longer than usual trip outdoors with them in my gloves, I found my palm to feel a bit off, maybe dry, it was tough to say exactly what it was. And for note I try to keep them on the lowest setting only, the others feel too hot for direct contact to me. For bare hands I might recommend something like the UT2S, as these provide little surface area. If it's not too cold out you can shift them around in your hand to cover your palm and fingers.

These are super fun little warmers. I usually use the hot hands disposable but I don’t like how wasteful they are. Bummer is only one side of each warmer gets hot but that’s the way they are designed and they do work really well! The charging cord is a bit cheaply made and hard to plug in but i typically just use my iPhone charger and that works perfectly. It seems to get plenty hot on the 2nd setting and I haven’t needed to bump it up to 3 (max) yet. Typically use at my child’s outdoor soccer practices when it’s around 40°F outside; but Colder with windchill.

Arrived on time and in perfect condition. I bought these for our family Christmas drawing and they belonged to my nephew until I guilted him into trading. They were then loaned to my son who went hiking for the week between Christmas and New Year’s. They worked wonderfully for him and heat up quickly. Nice inside my pockets. Not bulky or overly heavy. I give them a 9 out of 10, because nothing’s perfect. 😉

Purchased these for my mom for Christmas and she loves them! They heat up quickly and definitely keep your hands warm. Easy buttons that allow you to adjust the temp and turn them on and off. I was concerned the size might be large for her, as she has narrow hands, but they fit well. Well worth the purchase
