Cosyzone Hand Warmers Rechargeable, 2 Pack 8000mAh Electric Hand Warmer Power Bank, 360°Warmth, Perfect for Outdoor and Camping, Best Gift for Winter

The media could not be loaded.  It's a great little product I have bought the double pack so I came with two and once they were charged they worked very well they got so hot you have to wear gloves so I had dollar gloves fabric and it's perfect with that so you don't burn your hands they get that hot it does have two settings and you can switch between them fairly easily. Again I like the value I like the fact that these can double and charge other devices that become little battery chargers so they have multi uses but when it gets cold and you need something in your hand there's nothing better than this little device I love that you can grip your hand around it and it keeps your hand warm. This is already saved me several times cuz I work outdoors. If I had anything to say about it was that sometimes that the button is easy to activate the on switch. Normally you press and hold it for several seconds to start the heat but if it's pressed into something accidentally for several seconds it will start as well and there's been a few times when I've noticed heat inside my pocket and it was because I had accidentally pressed down the button for too long.again it's a great value for the price and I would definitely buy more and I may consider buying more family and friends.

These work great. Heat up real nice and good controls.I did not care for the shape/size. I have large hands/long fingers nothing puny by far.. These felt awkwardly bulky and uncomfortable in my hand. I expected them to feel relaxing, like the hold on a Hiking or skiing pole. No, it was like gripping hanble bars..Anyway, they didn't go to waste, another family member was happy to take them

Easy to use and they warm up quickly. Excellent gift idea for outside workers.

I agree with most reviews here. These are a bit bigger that what is practical for me and the button does get pushed super easy in mittens. It gets too hot on high setting. I want these smaller with a different button and then I would rant about how great they are! I love my smaller square ones but I would prefer this cyclone shape. If you have big hands, these may work for you.

Good product with good quality , but with a big flaw.If you keep it on a briefcase or a backpack, in my case a sling backpack, the power button can accidentally be press on with you don't even notice it.Also would be great if they come with invividual sleeves to hold them.

A great hand warmer set for a reasonable price. The only complaint I have about the product is its on/off button placement, which can be annoying sometimes as you might switch between the heating levels or turn off the device altogether while having it in the pockets.

Heats up well. High seating requires gloves. Not very good as a charger. Drains very fast and doesn't charge phone up beyond another 20%. As a heater battery lasts a long time. will come on accidentally in pocket or bag, top button is sensitive.

I'm a bit sad because I bought a set of these for myself, but I also bought some to give as gifts; one for my mom who lives in a very cold area and walks daily and the other for a skier. I work in a very cold studio, so I thought they would be great for warming my hands. At first, they worked great - too great. They were so hot it was uncomfortable and I couldn't make them less hot. The next time I used them, they were a comfortable temperature, but stopped warming after about 1/2 hour. Now I find that I take them off the charger and the light immediately flashes red. They warm for a few seconds, then go off again. So, I'm afraid I might be sending dud gifts to my family. Oh well, it's the thought that counts, right?
