HotHands Body & Hand Super Warmers - Long Lasting Natural Odorless Air Activated Warmers - Up to 18 Hours of Heat - 3 Individual Warmers

Works great and stays warm for many hours !

Shook the package for 20 seconds and it stayed comfortably hot for about 8 hours. Great.

My grandkids loving getting these as gifts. We live in Michigan and being outdoors in the cold is 8 months out of the year reality. Great for hunting, early season baseball games, soccer, football season and weekend camping trips. We always carry some in the vehicles - you won't get cold if you are prepared !!

Very good product, long lasting

I had a bunch of these in my junk drawer that went bad by the time I went to use them, so I had to pick up more. The ones I got were fresh and had a manufacturer expiration more than 1 year out so they look pretty fresh.The hand warmer took about 30 minute to get to full operating temp, which was about 130*, and held that temp for a full 6 hours. Even at about 8 hours I noticed some heat but it started to die down around 120* and that was when I stopped testing and recording the time and temp logs.While I still prefer my zippo refillable hand warmer (which I just fill with VM&P Naptha from the hardware store since it’s the same as zippo fluid at a fraction of the cost) for day to day use in the winter since it saves if landfill trash - these still have their place. Since I have a dozen extra after my intended usage, I made sure to load up the cars and emergency kits!

Use them at the game, fishing, or to keep your urine warm for a drug test.

It's a hand warmer and works

Okay this product might not warm your heart but it will warm you up and it literally lasts all day I put one in each pocket on cold days and they stay warm all day and when your working with your hands all day I cannot stress enough how important it is to have a quality product like these to make sure your hands stay warm dry and attached to your wrists. At this price I will be using them on every cold day from now on
