Lentra Hand Warmers 80 Count - Safe and Odorless Single Use Air Activated Heat Packs for Hands, Toes and Body - Up to 10 Hours of Heat - TSA Approved

They take a while to warm up. They warm to the correct temperature. Mine lasted about 4 hours. Easy to use in your pockets or in your gloves.

These sachet warmers are just the right size to fit in my palm. With gloves, I can still use my hands. They take about 10-15 minutes to warmup after you take them out of their package and shake them. The more you shake, the quicker they warm up and the warmer they get. The heat lasts hours but not all day. The price is right.

I think they take a little longer to heat up than the name brand ones, but heat up just as well. A little bad english on the back. Normally that would worry me but these kept my hands toasty as I used my snowblower for 30 mins. Still 5 star despite bad spelling on back.

Lower price than HotHands, and does the job. Not as comfortable inside gloves because they seem thicker and more bulky than HotHands, and they don’t seem to last quite as long, but still stay warm for several hours (might just need a new pack on the late afternoon if you’re out all day).

Very convenient to slip in pocket or glove. Easy to activate, just shake. It does take a little bit of time to heat up but keep in hand or pocket while activating and you’ll be amazed the heat you get from it.
