HotHands Hand Warmers - 40 pairs - 10 hours of heat - Air activated - Ready to use, 8368342, Orange

These are one of those things you do not realise how handy they are until you really need them. I grabbed the big pack to keep around for winter walks, outdoor jobs, and the odd freezing commute. You just open the packet, give it a shake, and it starts warming up on its own. No charging, no prep, just chuck them in your pockets or gloves and forget about them. The heat lasts ages. I have had some going most of the day, especially when tucked into a coat pocket. They are a decent size too, not bulky, and easy to carry in a bag just in case the temperature drops. On the downside, they can take a few minutes to properly get going, and once they cool down that is it, you cannot reuse them. They also get warm rather than hot, which might not be enough for extreme cold. Overall, they are reliable, simple, and great value in a multipack. Perfect for everyday winter use without any fuss.

These are unbelievable! Still uncomfortably hot (shirt pocket) after 13.5 hrs. What a fantastic product. 10 hrs would be amazing but I'm now heading for 4 bonus hours...incredible! Will it ever cool off? Started it at 5am and its now 6:43pm. Just gave it a good shake and at long last its not hot, just warm. So 28.4p for almost 14hrs - what a bargain. One down 79 to go ...

Excellent and they work for 8/10 hrs.

These work! Lovely warm hands and they last all day.

They don’t seem to heat up well in the open air. That’s why I’ve deducted a star. For better results, keep in a pocket or within some kind of fabric and it’ll get your hands pretty toasty. They have also lasted around the 10 hour mark when not left out in the open.

My daughter loves these. She uses them in school most days. Great value also for the amount you receive. Nice product.

They are absolutely amazing. Keep.me and my children warm. Very happy with it. Thanks.

These are brilliant in my gloves while out walking dogs, or seeing to the horse at the yard keeps my little hands toasty. Well worth the money last from morning walk and yard to afternoon walk still hot .
