The item works as advertised! The handwarmers are small, portable, pretty, and easy to use. I haven't been able to test out the battery life yet but I'll update my review if it's bad. The durability of the warmers is questionable. I accidentally hit it against something in my car and the metal part became damaged. There wasn't a lot of force used either (one star was docked). Only the metal part of the hand warmer heats up and I wish it did both sides (I know why it wouldn't work logistically). The magnetic side is super convenient for traveling and keeping the two warmers together. Overall, this would be a good holiday gift or something to give a friend moving to a colder place!

Good size to fit snug in my palms (I wear size M in women's gloves). They get warm super quick and so far I've never turned it up to the highest; low always does the trick. The best part is how the two warmers are magnetic so they clamp together back to back so you can wrap your fingers around and have even more skin touching the warmth. I'm thinking at some point I'll buy another pair. Recently took a winter walk and when one of the kids took their gloves off to play in the snow, then wanted to go home early "because my hands are too cold!" I whipped these out of my pocket and the kids were so fascinated with how toasty they were, pretty soon they were all claiming their hands were freezing LOL

Nice, compact hand warmers. Easy to use and charge, they fit perfectly in a pair of gloves, with three heat settings, and each come with a lanyard you can strap to your wrist if desired. They also attach to each other magnetically if you'd like one larger hand warmer. Overall, very pleased with these.

This product does what it says my husband tried these out abs he said that on the high setting it was super hot, so he kept them in his pockets on the low settings and that on one full charge low settings lasted his full 12 hours shift. They are very durable and made from great material, and small for transport and storage, works great, long battery life.over a great product for the price.

Cute small hand warmers that pack a punch. I personally find level 1 (lowest temperature) too hot to place directly against my skin, but like having them in my mittens to warm the air around my hands. Also, when I'm wearing two pairs of socks, I stick the warmer between the two layers against my inner calf which warms up the blood going down into my feet. This warms my feet without having to fit the warmer in my boot which would be uncomfortable. I am pleased with the battery life and features of the product. My only complaints would be that the heaters are too hot, and also that it is easy to accidently press the button to change the temperature during use.

These handwarmers really are the bomb! I am always cold in the winter and I put these in my pockets each day and they keep me warm all day. There are 3 settings, I use setting 2 and it lasts more than 8 hours. With quick charging. Best part is I'm not throwing away the disposable ones each day which is less waste and less money!I bought several pairs for Christmas presents and all recipients love them also!!

Small and lightweight. I put them in the zipper pouch of my ski gloves on low the first time. My hands didn't feel warm, but my fingers were not as cold. The next day I set them on high. Again, I didn't feel them as being warm until I shook my hands which distributed the heat to my fingers. I took off the gloves and found my hands were sweating. So they did work. However, when I took them out, they were so hot that it burned my hands. I won't be using that setting ever again. I have used them to rub on the bottom of my feet with socks on, and it did take the chill off. The best use was in bed. My feet were cold under the covers so I put 1 under the sheet. Within 5 minutes my feet were toasty and I removed the warmer. Excellent overall. But a fair warning that the high setting is extremely hot.

I didn't really need these and neither did I really want to spend $20 on them. But I read the reviews and took a chance and there was a discount if I remember correctly. They are tiny (a guy's hand might need bigger ones) and comfortable. And, my favorite, they are rechargeable! They have three heat settings but I have only used the lowest which I found adequate. I find them particularly handy when out walking and taking photos. I don't have to struggle to get gloves off so that I can snap a photo. They also warm up my pockets. The only heat on one side but they click together magnetically for storage in a nice little pouch.

Man kann die Wärmestufen einstellen (3Stück an der Zahl)Akku hält lange, wie lange kann ich nicht genau sagen. Aber definitiv einen kompletten Tag draußen. Nach 4 Stunden (30 Minuten volle Leistung, 3.5 Std mal auf Stufe 1 und 2) nur weniger als 1/3 aufgebraucht.Auf Stufe 3 sind die wärmer wirklich sehr warm. Auf purer Haut nicht allzu lange aushaltbar. Aber wenn man überlegt, dass man ich die Stufen selbst einstellen kann so heiß wie man will und so wenig wie man braucht sind die echt perfekt.Auch sehr praktisch und ein klarer Vorteil gegenüber den Handwärmern mit Gel und ,,Knickchemie".Kan. Ich wirklich jedem empfehlen der lange draußen ist und es gerne warm mag.Handgelenkschlaufen sorgen für Sicherheit. Man kann sie nicht verlieren.Liegen gut in der Hand und können tatsächlich einfach in den Handschuh gesteckt werden.Schön klein aber trotzdem die ausreichende Größe um zu wärmen.Bin super zufrieden.Gleich 2x als Geschenk gekauft
