Bought for working in a warehouse. Love their shape, fit nicely in the palm with a glove on. Love how fast they heat up so if you just need a little warm me up, they are fast to help with the process. but they also last at least 6 hrs. on low. They get really warm I have not taken a thermometer to them, but they get plenty hot enough.

These are rechargeable hand warmers that fit will in my gloves or in my pocket. I like that there are no batteries. There are 3 heat settings. Really good purchase for winter soccer in AZ.

I gave these to my partner for Christmas and they have been a great tool for him at work where it’s cold. The battery life for them is exceptional, we noticed recently at the lowest setting it stays warm for upwards of 14 hours. Great fit for your pocket, easy to charge and store while not in use. Over all a great purchase.

I first want to just say that these hand warmers are amazing. I bought 2, one for me and one for my man. We hunt a lot in the cold... When I tell you these babies came through every single time... I mean it. Battery life lasts for a longggg time. I like they give you the double charger to charge both hand warmers at the same time. It has 3 levels of heat... I only can stand level 2 and that's if it's extremely cold. Level 3 is extremely hot. All in all, it's funny my man was seriously trying to disrespect them and saying he doesn't need hand warmers he's a man. However, all of his hunting buddies keep asking me where I got his warmers from because they saw him using his. 🤣🤣🤣. 10 out of 10, I highly recommend.

Product overall is nice. Low last me 11hrs, high lasted 6hrs. Now I'm comparing them to the Ocoopa ut3 pro. I used them for hunting & i only wear a liner glove no heavyweight cold winter glove. Temp was 16°F with wind chill factor feel like was 4°F Did they keep my hands warm absolutely but I had to keep the on level 2 and turn them to warm my fingers. Only true down side was the feel & durability. Obviously not made for this but I hunt 20-25ft up in a stand and yes I dropped it out of my pocket. Unfortunately the plastic broke. There is no drop rating so I get it just giving you real world situation. I used these as my goto until I dropped it so being fair I pulled out the Ocoopa and did the same thing but on purpose. The Ocoopa does not last as long but it does heat the palm & fingers at the same time on level 1 same temp. The Ocoopa is a metal housing and no cracks or broken parts picked it up about 4hrs later once it was dark and it was still on. The red light & orange color made it easy to find. So if your on ground level need longevity but don't care about durability this item is a great buy. I did actually buy another set for a Christmas gift so would I buy it again absolutely. This product is great if your taking a walk or in an office setting but get cold hands. I'd give it a 4.5 but not certain how to get 1/2 star

My husband has used these during hunting and being outside this winter. They’re small enough they fit well in the pockets and within the hands but stay warm for awhile. For the price, they work great!! Definitely will recommend them to anyone.

This is a must have, especially, if you have to wake up early & walk out in this cold weather. Had it on high and lasted 8 hours. It gets really hot and stays hot all day long. It's definitely worth getting 😁

I bought these warmers and used them in Iceland, with temprataures of -20 degrees C. They are ideal for freezing weather, the battery lasts all day, they don't take that long to charge, I would use them on my hands and insert them in different parts of my snow jacket, the size is ideal to use them in different ways. I was very happy with this purchase.

Under the cold weather. Very useful to use the product

Purchased for my daughter for Xmas. I have an older pair and have found that these last much longer, they get warmer and the units last longer. They are great as a battery back ups. I would recommend as a must have for the price.

When I tell you this is so worth it!! In Canada the temperature changes all the time I just keep them in my pocket and whenever I need it I just turn it on super useful and great to have all the time

Nice small hand warmers that heat for a long time! They really work well!

Convenient they charge with a USB and small enough that they are not awkward to hold.
