I ordered 2. One to keep and 1 for a gift. Great buy. I am enjoying mine so far.

Do use it occasionally and find it helpful. My hands are the first thing that gets cold.

One works well, the other one has a switch that is extremely hard to turn on. If you can get it to turn on - it gets very hot.

I bought several, some are a bit warmer at level one than others yet they work well. The sides of these warmers are a bit slick. That being said, these hand warmers are durable, meaning I've dropped them a few times not on the concrete,though. Again, I like them.

I ordered 2 of these, one in 2019 and one in 2020, and one is totally dead already and one has basically no battery life left. I guess it's not surprising at this price point and since heat is bad for batteries. They work well as a hand warmer. The micro USB plug is not well mounted and they are very hard to plug in.

These are cheap. The charge doesn't last a long time but for an early morning round of golf and only needing them for 7 holes at the most it works.

I like this hand warmer but the shape of it isn’t perfect to hold in hand. I did keep it because it warms up fast

Takes a long time to charge, so you are left cold when it runs out of power.Cover is necssary, even at lowest heat level ... but delevers all the heat you could need.
