AI Hand Warmers Rechargeable, AaoLin 2 Pack Electric Hand Warmers Reusable, 12Hrs Long Heating, Portable Pocket Handwarmer Great Gift for Outdoors, Camping, Golf, Hunting Gear

They work amazing, especially if you only need them to go in your pockets.Son works in a warehouse freezer & doesnt get a chance to put his hands in pockets but says they are nice to have on his breaks to warm up. They are to bulky to fit in gloves.Can get hot enough to burn if left on skin to long.Will buy again

I first bought a pair of these over a year ago - LOVED them: they lasted for several hours between charges, and were the perfect size for keeping in a coat pocket...one in each pocket. A couple months ago, purchased a 2nd set and this set needs more frequent charging, doesn't last as long between charges, even though used under the same situations (normally on heat level 1). Still a good product but not as good as the first set I bought. :-(

Charge fast, last a whole round of golf on med. I liked so well bought 2nd pair for son!

It came on time first Christmas. I love it, small enough to for perfectly on the palm of your hand.

They get the job done keeping your hands warm, but they're a lot smaller than I thought literally fitting in the palm of my hand. They can get quite warm which is good if you're in extremely cold weather, however living in a temperate region like myself it made my hands start to sweat. I can't complain though since they get the job done.
