The best purchase I've made for myself in a long time. This little magical thing helps so much. It is the perfect size for my hands and feet, and toes. It came with enough battery life to try it out. It heated up immediately when turned on and a good amount of difference in heat levels, though once I let it warm up all the way on high and turned it back down I didn't really notice a decrease in heat, but I'm okay with that. This warmed up my purple hands in just a few mins. My feet and toes took a bit longer to warm up but that's just because they are mostly dead in the winter.
This is an appendage saver. Thank you so much for a wonderful product. I will up date if my opinion changes, but I doubt it will. <3

Don’t know how I ever lived without this device. If you have circulatory problems or just a very cold office, YOU need this device!
Highly recommended!

Really nice, handy product (haha). One of my dialysis patients recommended this product - works good for those who plasma donate too, to keep your hand from getting cold. I bought them for my husband, who has zero body fat and almost dies every winter here in Minneapolis, and he's quite happy with them too!

Love, love, LOVE!! How have I not know this existed until now?! As a sufferer of raynauds, my hands are always freezing so this is pretty much a life saver! I work as a letter carrier so I'm often outside in rain, sleet, snow, etc. but can't really wear gloves because it makes it near impossible to deliver the mail. This is seriously the best thing in my life right now!

I haven't even gotten to the fact that it also can function as a powerbank too!! Take all my money!! I didn't know what true love was until now!

I have arthritis that hits my hands hard. I have looked long for something that would easily warm my hands and ease the pain of arthritis. Plug in heat pads are too bulky and you can’t take them with you. This hand warmer is amazing! It has three levels of heat and level one is plenty hot. It really works. And at such a great price! I highly recommend this devise.
Definitely going to show it to my rheumatologist at my next visit!
