Great hand warmer for the price. it is a bit bigger that I thought; roughly the size of a hockey puck. Had to charge it up before I could use it. It takes about 2-3 hours to fully charge using a 5V 2A power adapter (I used the Samsung charger that came with my phone). Battery life was about 4 hours? I lost track of when I had it on and off since this thing gets really hot. It only has two heat settings with low being about 50 degrees Celsius and high being 60 degrees Celsius. Would have been perfect if the low temperature was a bit lower and had more temperature setting.

It's warm & can charge devices. Still seeing what the battery life is like after multiple charges, but it's helpful for winder days

Takes time to warmup, but quite handy.

Great hand warmer, though battery life is quite short.

The product is as described and is even warmer than expected. I bought it on sale and am happy with the price, but I wouldn't have paid full price.

Very useful.
