Bought for my dad and he regularly works in cold weather.Pros --Small and easily fits in your palm-Heats up extremely quickly, ~3 seconds to get up to desired temperature-Conductive material is not ceramic so it does not hold heat, but due to battery life of devices, this is not required andmy dad and I prefer the quick heat up time-Can get very hot on high setting-Good battery life considering the heat it is generating-Magnets in the back to combine both hand warmers into a bigger hand warmer to head up palm and base of the fingers.-Easy to useCons --Would like a faster charge timeOverall - Great product which is worth the money. Would recommended to anyone. My girlfriend and her dad have also this a great product

Bought as a Christmas gift & given yesterday to a friend who suffers from cold hands a lot of the time. Both the really cute hand warmers were in a strong little box which was cellophane wrapped. Inside, the warmers were in separate soft plastic bags within an indented plastic tray & underneath this, was the USB charging cable & instructions. The items came already charged & so could be used right away. They each have 3 levels of heat marked with a tiny red light which can be changed by pressing a button. 1- mildly warm, 2 - medium & 3 - very warm. They heat up very quickly & my friend is delighted with this gift. Excellent product!

I’ve tried a number of different handwarmers and these are by far the best. Not too big so you can comfortably wrap your hands around them, a range of settings (the highest is very warm) so you can find what’s best for you, reasonably priced, and good build quality. Haven’t needed to charge yet so can’t comment on charge time. My only issue is that because they stack magnetically they ‘top and tail’ as it wear which means the loop holes could ideally have been one at the top, one at the bottom so you could attach together to a lanyard.

I have Raynaud's disease so my fingers lose blood supply in the cold, are white freezing & uncomfortable. Have bought hand warmers before but not brilliant. However these ones got really hot, so my entire hand & fingers were lovely & warm for the entire duration of my walk. I’m impressed. Worked for me!

Brought to use in the office, rechargeable with small usb cable which charges both at the same time or just one on its own, a firm press turns the devices on and because of this they don’t appear to be able to be accidentally turn on, they have different levels of heat with the highest being very hot, I find my hands get really cold and these are just nice to keep with me and keep on low at the desk or attending meetings, even use them in the evenings if it starts to get a bit nippy, they come in a little flocked bag that’s big enough for the devices their wrist straps and the charging cable, I chose blue it’s a nice colour, so far, so good,

Fantastic buy for the cold winter weather. Fairly quick to charge and keeps a charge for a few days. I find I only need to have them on the first setting. Good quality product.

Better than expected! I use these when I'm fishing to keep my hands warm, an absolute game changer, the no.1 setting is so hot I've never used it on other settings and they keep hot all day. Amazing product!

Omg !!! These are the best things ever !! They are so very easy to use,heat up instantly and the perfect size for just sitting in your hand . I can honestly say i wish i had bought these years ago.Worth every penny and more.
