Lifesystems Reusable Hand Warmers, With 45 Minutes Of Heat, Perfect For Pockets When Camping, Hiking, Skiing Or Walking

These are great handwarmers, I looked into USB/electric rechargeable options initially but this is a far better solution. Not only do they recharge without needing power, it's a kinder to the environment approach. Having read how they work it still sounds like magic! The picture is of them after use - they are liquid and pliable until used then they are solid and opaque. Value for money, Ease of Use

The heat from the warmers are more than able to keep hands warm for up to 20 mins. The flexibility when first activated means they can be adjusted for all hands so they are comfortable for all people. The quality of the plastic on the outside can rip if caught on a sharp surface, the size if great for an average sized hand. Overall they are great for going outdoors and good for money.

Great heaters, but phew!! they get hot.

I haven't had them long enough to rate them properly but I used them this morning and found them very good for about 25 mins. I put them into boiling water for 8 to 10 minutes until they were liquified but found after a while they had gone solid again ... so I put them back and boiled them again and they seem to be ok now ... see what happens next time

These last 20 mins MAX. Total waste of money - you're much better off with the disposable types or USB battery units.

Great for keeping hands warm on a winter walk or even at home during this cold spell.

The media could not be loaded. Excellent little hand warmer and appreciated giftWith Winter always upon us or looming around the corner, or merely for those random cold days having these hand warmers really is a pleasure.We personally store one in each pocket of our thicker coats, reason being, when you head for those thicker coats you know its going to be cold (Possibly a bad idea if it rips or leaks - although we have yet to experience this). On those freezing walks its a pleasure to suddenly remember you have one of these in each pocket!They heat up well, however in my experience not blisteringly hot. The colder it is outside the faster the heat obviously dissipates. I would give it a solid 30 minutes and thereafter the warmth is somewhat lack luster.As per the video, simply snap the small disc and within seconds the pack will solidify and heat up.To re-use/reset the hand warmer I personally bring a pot of water to boil, place a hand towel or similar on the bottom so the metal is not directly touching the plastic and as such melt it. Pop the hand warmers inside and wait for it to form its gel-like state again.Pros:> Easy to use> Can be safely stored and used when needed> Provides decent warmthCons:> Warmth only lasts for around 30 minutes> Resetting / boiling them to re-use them can be an annoyance
