Brilliant
These heat up instantly and get lovely and hot. The shape fits into my hands perfectly and my daughter also finds them comfortable to use (7 y/o). Feel very nice quality and love that they have magnets to keep them together, wrist straps and a carry case for when not in use. Very portable and I will take these everywhere with me. Cannot comment on the battery life yet as I charged them on arrival and have used for one week on school runs but it seems reliable. Has a blue light indicator to let you know the battery level so you can check and charge ahead of time. I’m a pink person and I love the colour of this. Fit my aesthetic perfectly. Will be buying another set for my daughter

Good battery life on lowest setting which was plenty warm enough.
Very happy with the battery life and the heat output. The middle and high setting should probably be used with a a glove between your hand and the surface of the hand warmer as it gets up to high 40 Celsius. The device remembers the last used setting when next turned on. Simple operation. The two hand warmers come with special made up cable to charge both at the same time. Be sure to use a good charger. Interesting on the lowest setting using it entirely in my coat pocket and with my hands holding it about 50% of the time it lasted about 5 hours. This is because it cycles through a 2 second on and 30 seconds off so you can feel it swinging between hot (about 40 Celsius) and cooling a little. This will probably be different when not holding it and depends on how cold it is around the unit but explains the supper long battery life out of a 2amp hour battery. Clearly much reduced as the on time is longer on each of these settings. Overall nice looking and seems to be good value when I purchased in November 2025

A must have for those chilly mornings when out walking.
I bought this hand warmer mainly when commuting to work on those colder days, I must say, I am genuinely impressed. I love the idea that it’s rechargeable to replace my disposable warmers, which makes it more environmental friendly. It gives 3 levels of heat but I find level 1 is enough to keep your hands warm without feeling too hot. When holding, the size is just right and feels When holding, the size is just right and feels comfortable. When turn on level 1, it gives at least 7-8 hours of gentle heat when fully charged, last longer than expected. I love the design tear drop design and various colours to choose from. Highly recommended. .

Heat up quickly
Bought these last winter and heat up very quickly. Perfect when using in pockets, however, due to an injury to one hand, my fingers get very cold even on mild days and the heat does not reach my fingers when I wear gloves, which in winter is a must. I have gifted them to a relative. They are a very good product just not for me,

Great Product! Absolutely in Love!
Great Product! Absolutely in Love with it. They also come with their own pouch for storage and the are magnetic, so they stick together. The battery lasts for days, depending on usage, and they do charge quick. Warm up fast and at a great temperature. Life savers for me.

Finally a gadget that works
These wee palm pals are a god send for people who have permanently cold hands. Whether it is from bad circulation, reynauds disease or just unfortunate biology, these have made a huge difference to me. I constantly wear gloves around the house no matter the temperature and certainly when I am outside but stil my fingers are freezing. These little butes are cute, and they work!!

Very warm
These have been great for the winter so far. The highest setting can actually get pretty hot if it isnt freezing outside. Very durable as well, they still work after being dropped many times.

Perfect on-the-go hand warmers. Highly recommend!
Bought 2 sets of these for an Alaskan cruise and they were awesome. They work really well and can get quite warm. I like that there is 3 levels of heat available. They take a bit to recharge, but they hold the charge for a long time. I was impressed with how long these actually lasted and never had a day where we used the entire battery up. You can either keep them in your pockets and hold them that way, or do what we did, stuff them into our gloves and kept them in our hands that way. We were on a whale watching cruise and did this and it worked great. It took a little bit to slide them into the glove, but it was worth it. The shape of these feels more natural to hold than another set my son used that was more straight like a broom handle. I would definitely recommend these for your cold weather needs. The other thing that is nice is not only are they USB-C standard, but the charging cable is a single cable port on one side with 2 outlets on the other side so you can charge both up at the SAME time. Very handy to have versus a single port and having to charge them up one at a time.

It’s okay ..
They get warm, it’s a bit of a hassle charging them asu charge them apart. The plastic outside also cracked because of the temperature difference as it was very cold outside. If it’s colder than 5 C it’s not the best. Otherwise if you often have cold hands this isn’t bad.
