Large Hand & Body Warmers - Up to 18 Hours of Heat, Super Long Lasting - Easy, All Natural - Air Activated, for Body, Hands & Toes - Odorless Hot Hand Warmer - Sport Temp

This stuff is AMAZING. I have a ton of spinal issues and deal with a lot of pain. Heat therapy really helps me so on an overseas trip with a 16.5hr flight I took these with and put them on my back. Man did they help. They actualy heat up to where you can FEEL IT and they stayed hot for longer than the duration of the flight. I was amazed and so happy as they gave me relief to help get through the flight. They do take a minyte or so to heat up but once they’re hot they work great. A must have if you run cold and have constant pain and can’t always plug in a hot pad or boil water for a hot water bottle.

Really like these! Does last 18+ hours when cold. Highly recommend! We discovered these again during the ice storm this year. Helped us keep warm when our power went out and our gas fireplace went out too. Great invention.

Love these! I have cold feet and I use one of these to warm them in bed at night in lieu of a hot water bottle or electric blanket. It stays hot all night. I hold it between my feet until they're warm enough and then just let it keep the area warm, occasionally resting my feet on it when needed. It can get too hot to have on your skin for too long, so just be aware of that. Already on my second box.

I’m dealing with a decreased circulation in my knee that is causing pain at rest and I wanted something to keep it warm longer than a microwave pack because it’s hard to get up and down and I am not always at home. So, these things work great. It’s just the right size to slip in my brace or wrap on my knee with an ace. It stays hot for an incredible long time. I have to have surgery but until then it’s going to be a life saver having these. These are also essential for emergency kits in case of power outages and injuries. Highly recommend these for E kits.

Takes at least 15 min to warm fully. But they get very warm and last for a long time. I use them for my toddlers hands when riding in the stroller and he hasn’t complained they are too hot. Overall a good product. They are not sticky.

Works very well but initially takes nearly an hour to start producing heat. I thought the first couple were defective but later discovered that they not start getting hot in one or two minutes the way the smaller ones do. They will produce heat for more than 12 hours once they get going. I haven't checked if they go for 18 hours, or if that 18 hour run-time includes the first hour when no heat is able to be felt. Otherwise, they work very well and I have been using the regularly for several weeks now with no failures or other problems. Open it an hour before you will need it so it is ready when you need the heat.

They are a great size and warm up toasty. Great value for your money

This is an excellent product--prefect size and long lasting. The price is right also.

Wurden bestellt für die kalten Tage, eins habe ich bereits mal ausgetestet und ich bin sehr zufrieden, erfüllt den Zweck und jetzt bin ich Frostbeule gewappnet.

I have a herniated disc in my lower back and I was buying heat those wrap around your waist heat packs for it from the drug store. This is way more affordable and they stay hot for a long time, 16+ hours

Going to put 2 of these on my generator before bed 1 carb and 1 on oil pan, tried it this year at -30C, 2 pulls and started with hand warmers, these are hotter and larger, should be perfect.

I use this product all the time in the arena and it works for 10 hours. Great size too!

Decent heat for about 12-14hrs.
