They really do stay nice and warm for more than 12 hours !

Best electrict hand warmer

Works great…built rugged, light is kind of a gimmick, works as a battery chargers BUT these are way too large for my liking.

i cant give it a zero ibought the orange models which were orange until this year ! tested them and loved them but all but never using until recently for hand warming , to then recharge only partly drained to find theres a apoarent issue and left for many many hours to see no charge was done and even lost the part of a charge i had left after maybe being used 2x so now since its a 2 pack are they even reliable over time to use as needed or just more junk thats overpriced sold at sams , does anyone even do a thorough test on this stuff or is it something to set your house on fire when the junk quits working and your rrying to get recharge on it all day not even knowing something quit insude but still shows 1 blinking light while on a charger , ? anyway 2x use and im sure no one standing behind the product

They Are Bulky. The light is good to have. They get warm, but to really be of use they have to warm your pocket. It's hard to get anything done with your hands in your pocket. I'm not a fan of the chemical shaker bags. Overall, I say “ Not Bad”. Would recommend to hunters, but not guys that are working outside. It's just something else to keep up with, for minimal results. A bit pricey for the results.

open the package charge them up. they sat for a couple of days as the weather had warmed up. I eventually grabbed one to test out the charging of my phone with the usb-c cable option and it did not work at all and thought that was odd so I tried the other charger and got the same issue no I know this is a good working cable but I grabbed a couple other cables and got the same exact result the phone was a Samsung Galaxy s24 Ultra. the USB a option works for charging my phone and other devices but the USBC was defective on both.

One work one time. It nor the 2nd one never ever worked. I returned!

They get very warm, your hands won get cold

I use them at work, the flashlight is also a nice tough. Battery life is great.

The hand warmers are not very good. When I tried to use them they don't get very hot at all
