Love the design and warmth. Suffering from Raynaud’s my fingers have been cold far too long. This device comes in handy. I recently purchased and took with me to London and Dublin for vacation. I used it on chilly walking tours and just days out and about. The battery lasted 3-4 hours on a full charge for me. I haven’t used it since so this is my first use estimate. I didn’t use the flashlight but turned it on to test. I bought some others that work well but definitely aren’t as cute as this one. Thanks for developing something fashionable yet functional. I’m buying more and recommending to anyone who gets cold hands/fingers.

I bought 3 of these for a ski trip to Switzerland. Gave one to my sister and swapped back and forth charging and using the other two. These were a life saver. They lasted for a good few hours. And heat up super fast when you turn them on. They heat up to the perfect temperature (that sweet spot before something gets just a little too hot) so you can hold it in your hand without needing to wear gloves. I actually tucked mine into my shirt over my heart and it helped a ton keeping me warm all over while riding up the chair lifts. (Maybe not recommended if you have heart issues or any of those other medical disclaimers) The strap is great for helping to keep track of them, the flashlight is a nice bonus, though I haven't really needed to use it. The backwards charging functionality is super handy too when your phone is on low and you just need a little bit more juice until you get home. They really are the perfect size to fit in even my tiny hands. I'm so happy I impulse bought these before my trip they were worth every penny.

My wife absolutely loves this hand warmer. It works well in very cold weather and makes being out in cold weather much more enjoyable. It is very small and fits in her palm perfectly and comes with a nice wrist strap so she can let it hang if her hands get too warm. It charges pretty quickly too.

I bought this hand warmer for my spouse because she gets cold really easily in winter. It heats up quickly and keeps her hands warm for a good amount of time, which she really appreciates. The rechargeable feature is convenient, and it’s easy to carry around. I wish the battery lasted a bit longer, but overall it’s a thoughtful and useful little gadget

I love this hand warmer! Seriously, I loved it so much I bought two more for Christmas presents. The first person who got one loves it as much as I do. She's usually not really excited about gifts but this time she really was.😊 i'll see the second person's reaction this evening when I gave her her stone.😊 There's so much to love about this Stone. It's smooth and comfy, perfect for warming your hands or even a sore neck, elbow, or wrist. It's lightweight, easy to use, and holds a charge well. 😊 The flashlight is awesome, too. I love the size and look of this stone. Actually, I'm getting another one for myself, and maybe a couple more as gifts because it makes such a great present. Bottom line – the price was great, shipping was fast, and everything – the stone, flashlight, strap, even the box – is gorgeous and exactly as described. The instructions are easy to follow. I totally give five stars for this wonderful lil stone. Thank you!

So I bought tis hand warmer as a present for my wife because frankly I was out of ideas and her hands were cold at the time. But I'm super glad I did. 15 seconds after turning the hand warmer on it was starting to heat up. A charge lasts a very long time. Days of regular use to be precise. She doesn't use it all the time but between stops when shopping or when she is out for a jog it's perfect. Fun surprise it uses a type C charger so no digging for an antique from my cord bin (you know the one that every guy has stashed so that his wife doesn't get rid of them.) aaaand it has a pretty bright flashlight built into the sleek design. It's stylish it works well and its cost effective. It works better than those smelly charcoal burners with the red velvet case that make every piece of clothing you own smell like that bag of popcorn that you left in the microwave too long. So go get one, maybe your next handshake will say look how good my handshake feels, and maybe you'll make the big promotion, you'll get a big raise, you'll install a pool and finally be the cool house on the block with a pool party every Saturday.. or at least your hands wont freeze. Enjoy

The Orastone Rechargeable Hand Warmer is a total lifesaver! I originally got it to keep my hands warm in my chilly office, and it works perfectly—quick to heat up and super comfortable to hold. But where it really impressed me was on a winter trip to Chicago. The double-sided warmth kept my hands toasty even in freezing temperatures, and the charge lasts a reasonable amount of time. I highly recommend getting two—one for each pocket—for maximum warmth. It’s compact, reliable, and so much better than disposable warmers. A must-have for cold weather!

Easy to use. Full charge in relatively short time - a few hours. Have had for about a year now and product still works great. The light function is good, but I don't use it that often. Gets quite warm without burning. I wish I would have bought two - one for each hand. We use it out in the snow and have had zero problems with it.
