They work great, maybe a little two big for some pockets. They take awhile to charge but last a long time.

Hand warmers charged pretty quickly and got HOT! It was so nice during those fall baseball games. Not sure how long the charge lasts, haven’t needed to re charge them yet. Definitely recommend!

Great product to charge your phones while on the go. Also good for warming cold hands. It is hard to turn the product on and off though.

Awkward control button. Not easy to turn on or select options: power level, light. Lasts all day on lower power setting. Good amount of heat. Very long to recharge. Lost charger cable and can't find replacement. Received one pair as a gift and purchased another pair. Called warranty to attempt to obtain replacement charging cable but not available. Flash light is bright enough have not attempted to charge anything from it.

The handwarmers do exactly what they claim. They heat up nicely. They have a decent flashlight function and they can charge devices . At $39.00 a pair I thought I was getting a deal. Imagine my surprise when I found the same item under private label at Walmart for $9.96 each. I could have gotten 4 for the price of two. ☹️ Well, any way, they work as advertised.

This is a good product, however, to turn on the different tools on and off, flashlight, warmer, view charge, is a bit difficult until you get the hang of it. First, the power button is black on black and very small, ironically, you would need a flashlight to turn on this flashlight. The other issue is the bulkly size, not very compact asa hand warmer. All in all, it still does what it's supposed to do.

Power button on one of the warmers malfunctioned immediately so I am unable to turn it off. Other warmer works fine. I like the idea and they seem to work good when power button works properly. Flashlight is brighter than I expected. I plan on returning item in hopes I will get two that work properly.

Bought these for my husband who works outside in the cold. He charged them as instructed but said they went dead within 10 minutes. Very disappointing

These handwarmers do get warm, but its very difficult to get to it go into warm mode. You have to click the difficult to press switch multiple times, and it inconsistently turns on. A simple small toggle switch or a flat press to hold or select mode switch would improve this product. Also the units will need to use the included USB C cable to charge. They will not charge with a universal type C USB cable. The product is not hateful- but it definitely needs improvement.

I bought a pair. Figured it would be a good option for a cold football game or maybe a brief hike or winter camping trip. Finally got the chance to try them out. Underwhelmed. Gave one to my husband and kept one for myself. I think the power button is defective on the one I used. I had to push it in really hard to get it to work and then have to pry it out as if it gets stuck. It is weird. Actually, I do not care at all for the on/off/heat-setting/double-click for flashlight all-in-one button. I would much rather there be 3 buttons. Power level 1 is plenty sufficient heat output. I just think that I am better off to get a whole box of those disposable hand-warmers because I don't see these lasting long enough to be worth the nearly $40 spent for the pair. At one point I accidentally turned on the flashlight and eventually got it off. One time I was trying to get the stuck all-in-one button to behave, and I had accidentally shined it in my husband's eyes while he was driving. It is bright I will give it that. It is warm. I will also give it that. I just don't see it lasting. I give my husband's a 2 star rating. I give the one I used a 0 star rating. Average out to a 1 star rating. I charged both entirely. Lasted the whole 3 hour football game plus around an extra hour. Then started acting weird like it was dead. I don't see them lasting 24 hours. As for a winter camping trip, I think the disposable hand warmers will still be the better choice.
