Hand & Toe Warmers - Variety Pack, 30 Pairs Hand Warmers, 10 Pairs Toe Warmers With Adhesive - Safe, Easy, All Natural - Air Activated, Body, Hands & Toes -Odorless Hot Hand & Toe Warmer - Sport Temp

Used these during a week long trip in the artic with 0°F to 27°F (-17°C to -2°C) weather. During the very cold nights, the hand warmers worked very well. They turned on after some shaking and I just stuffed them into my gloves. They didn't reach my fingers, but a bit of hand exercises to get the blood flowing and they would also feel some of the heat. Would probably work better with mitten style gloves? I used them with no gloves too and they were very nice and warm on the hands and face. I did turn some on on a not so cold day and they felt incredibly hot, but I put them in my pocket and would occasionally touch them. They stay on for a long time and easy to reactivate. I used the foot warmers twice and they also worked well. I did not feel the cold when standing on the snow and I did not feel too hot when in a not so cold place. They stuck to the sock well and peeled of easy. They did feel a bit weird at first because it's something extra on your foot, but I forgot about it once I was out and about.

They work great!!!

I buy these every year for my blue-collar husband who works out in the harsh weather in the wintertime. Large pack for a great price!

I feed community cats and placing these under their water bowls kept the water from freezing! Very easy to use and effective!

Not as good as Hot hands but they work.

I am the director of a food pantry in Arizona. I have about 50 volunteers, A number of them work outside early in the morning- lately in temps at the high teens or low 20s. They love especially the hand warmers.

My son was a mail carrier and it was brutal during the snowstorms and-22 degree days in Nebraska. This was his birthday present and he was happy to have them.

Not sure if the whole box that I received is faulty but some of the hand warmers don't get warm at all and the ones that do get slightly warm for a couple hours. The toe warmers get warm but they also don't last very long.
