Very effective and warm your hands nicely.
Awesome hand warmers. Heat up quickly and get nice and warm. Inside your gloves they get hot. Keeping your hands nice and warm. They come charged and last several hours. Received them quickly. Would buy again.

Best hand warmers
I am so glad I bought these. They have already paid for themselves vs me buying the disposable hand warmers. They have 3 settings and they heat up quick. They seem to stay charged through several days of use. Easy to charge. They come with their own little carrying pouch. Highly recommended for those of us that live in cold weather and want to keep your hands warm. On a side note, when I go camping in the spring and fall, I'm taking them to put in the bottom of my sleeping bag to add a little heat for my toes.

Very warm, love them!
Love these hand warmers! There are 3 settings and I only use the lowest. Other wise too hot. They last several hours between charges. I wish the entire surface heated, but the flat side does not - only the convex side. But it's great that with the magnets you can stick the two warmers together and just wrap both hands around the joined unit. I think this was a very good value.

A good hand warmer with a handful of small shortcomings
I’ve been using these OCOOPA hand warmers for a little while now, and overall I really like them. They definitely get hot — I’d guess close to the 125°F they advertise — and that temperature is perfect for actually warming your hands. As someone with mild Raynaud’s, the heat really does make a difference, and these offer quick relief when my fingers start to go cold. The downsides are mostly around practicality. The battery life is fine, but the charge time feels slow. When I run them on high, it seems like they take almost as long to recharge as they last. The included Y-shaped charging cable was a nice idea in theory, but one of the two output ends on mine didn’t work at all, so I ended up charging one side at a time anyway. OCOOPA’s model system could also be clearer. The numbers (3, 4, etc.) feel random — if the “4” is supposed to be better than the “3,” I really can’t tell how based on their descriptions. On top of that, the sizing isn’t consistent: some models list measurements in centimeters and others in inches. It makes comparison way harder than it should be. For larger hands, these are on the small side. They still help, but they don’t fill your palm the way I’d like. I also ordered another OCOOPA model with heat on both sides and I prefer that one. Its a nice feature that warms more evenly and works just as well overall. I’d recommend a 2-sided model if you’re deciding between the two. One major downside of both models is the size. Yes, small makes them portable and easy to fit in your pocket, but these do not work great for people with large hands. Still, the heat output and reliability make this a solid 4-star pick — great for cold hands and Raynaud’s, with room for improvement in design and charging.

Uncomfortable, but amazing.
These things get HOT, even on Low and last a decent amount of time. Unfortunately, they only get warm on one side unless you put them together. I have a pair of glove that have a pouch for hand warmers, and they are a bit too rigid for them. They work better if I put them in the hand part of my glove instead of the warming pouch area. If you n3ed something cheap, functional but uncomfortable, these are GREAT.

Amazing product, very pleased with purchase
Purchased for a friend of mine during the cold this past winter. They were everything advertised and she loves them. The quality was excellent, price imo was amazing for the rechargeable warmth given. She is a teacher and carried them every day after receiving them this past winter. One thing not advertised, we were video chatting and she told me she had a headache and rubbed her neck as if the headache was originating from the muscles in her neck, maybe from working on a computer for a long period through the day. I recommended using these hand warmers as a heat source and placing them on her neck. She said the heat generated helped tremendously in relaxing the muscles in her neck and ultimately her headache. The size, portability and magnetic construction helps her keep them in her pocket or bag without adding noticeable bulk to her what she already carries daily. Highly recommend this product and there are several different colors also, in case men would like some but maybe don’t want the pink color

Best hand warmers for cold hands.
Must need for traveling in cold. Battery lasts a long time. They come pre-charged. They come with a wrist strap which makes them easier to carry and versatile. Good durability. They have different heat settings in case the hot is too hot.

I really like them
They work really well. Warmth on level 1 is pretty good for most situations. Level 2 is good when extra cold or windy out. I have not needed level 3. Battery life is decent for being a heating unit. The first one or two charge cycles didn't last as long but the battery has been great since. Still need a backup, like the iron oxidation packs, if you are outside for extended periods. The size and curvature fit my hands well (For reference, large size nitrile gloves and most regular gloves fit snug & smooth on my hands). To warm my whole hand I prefer holding the pair in one hand (they only heat on one side). I liked these enough that I bought a second pair for my other hand. I also bought my neighbor a pair, and spare pairs for my wife & hunting bag. Watch the price for a while. First pair was 30+ bucks, but the rest I caught on big discount that was almost half price.

Gut für Frostbeulen
Wir haben uns diese kleinen Taschenwärmer besorgt, weil wir gerne und viel draußen unterwegs sind (auch bei kaltem Wetter). Die Handwärmer sind handlich und werden schnell warm bis sehr warm. Würden wir definitiv wieder kaufen!

riscaldano molto bene
Questi scaldamani sono ottimi, si ricaricano abbastanza velocemente e durano a lungo. Sono molto caldi, hanno tre livelli di riscaldamento ma io li metto sempre a uno perchè già così sono caldissimi.
