Hand Warmers - Up to 11 Hours of Heat, Super Long Lasting - Easy, All Natural - Air Activated, for Body, Hands & Toes - Odorless Hot Hand Warmer - Sport Temp

GREAT VALUE ON SO MANY! THEY WORK WELL AND WITH A LITTLE SHAKE--HEAT RIGHT BACK UP FOR A LITTLE LONGER. Purchased for outside feral cat houses in the bitter cold and they WORKED!! I did not know what to do with the extras, but found out they expire 3 years from now!! GREAT DEAL!!

Best product for someone like me who can’t wear socks. Used it all winter.

After activating a bag it stays warm for many hours. The heat is not high- but if you leave it in one place (e.g. your pocket or inside a glove) it gets warm and does the job.

These are the best hand warmers I have used while skiing. I often put them in my ski boots as I drive to the area, then put them in my gloves and sometimes they are so warm I take them out and put them in my jacket part of the day.

Sport Temp 45 pair hand warmers:I opened the box upon arrival, carefully separated one pair, keeping half for future use.Shaking it for several minutes produced a slightly more than lukewarm temperature- but with consistent occasional shaking, it gradually got warmer, but I wouldn't call it "hot" by any means. After keeping a toasty warm level for 6 hours, I decided to put it in an airtight plastic bag to halt the chemical process.Several hours later, I opened the bag, repeated the shaking until it was warm again, and got an additional 5 hours of use.It went back into the plastic bag overnight. The next morning, I opened the bag, shook the package, and it again warmed up, though not quite as much as initially. More shaking produced more heat again.I expect this will continue to activate for -- who knows how long -- instructions on package DO tell you to reshake if it cools.Going into the second day of use, the warmth is still there with intermittent shaking. This has exceeded the 11 hours of "warm" use, albeit with spurts of cooling and shaking.This is my experiment. When it stops working, I'll toss it and open another.Overall, I am pleased but wish it got hotter. No matter, I count these packets as useful and you can place them in clothing next to your skin and benefit without having to spend lots of $$ on an electrical room heater, or at least spend less $$.I hope this review has helped you.

I think these last much longer than the ones I used to have! Perfect!! I put them in my gloves as I snow-blow! Absolutely wonderful . Give them about 10 minutes after you open the package and shake them.

My kid uses this for school in winter time and it’s perfect.

They work great!
